Lenticular Clock
- andrewla 2y agoI'm most blown away just by the very existence of lenticular sheets -- I didn't know that this was a general-purpose thing that you could do at home Years ago I paid for a 3d lenticular photo print but I always assumed the technology to do so was out of my reach.
- ljf 2y agoI took a photography course in the 90s and we did some 3D images that you looked at two photos through a viewer or by going cross eyed. The teacher tried to get us to invest in some lenticular pictures but the cost for a 16 year old was just too much. As I understood it back then, they cut your 2 images into very thing strips and then interleaved half of them. I'd not thought of it much since but of course it makes sense that a good photo printer and the right software could make this all far simpler.
- stavros 2y agoThis is really cool! I had no idea you could just buy these sheets, I always thought you have to make them specially. The fact that you can buy them and then print a pattern is amazing.
- calebm 2y agoI love lenticulars. I'm working on writing my own lenticular software right now. You can see some of my lenticular math art here: https://gods.art/ https://gods.art/
- silvershell 2y agoAmazing work!
- JKCalhoun 2y agoI did some experiments creating lenticular 3D and failed miserably. I'll look at what you got. I would love to see the software, BTW.
- theferalrobot 2y agoThose are amazing! Are you hand aligning those lenses on the print or is there some sort of tooling/hardware/service that is capable of it?
- calebm 2y agoHand aligning is the only way I know of.
- mordechai9000 2y agoAny chance you could share the math behind the pixel snowflakes?
- hnlmorg 2y agoI’d love to know more about the floating exclamation mark in one of those pictures you’ve linked to
- calebm 2y agoI just walked into the room and that was there. After some examination, I realized it is a projection of the forest behind our house shining through a crack in the window.
- dr_kiszonka 2y agoI love the Give and Take one.
- alt227 2y agoWhen I click on a piece of art on your website it takes me to a page with an unhappy face and a message that says "No video with supported format and MIME type found". Using Firefox 129.0.1
- mkesper 2y agoIt's a MOV tagged as video/mp4. For me, FF recognizes only the audio part but if extracting the raw video URL I can play it with vlc.
- Hello71 2y agoThey're the same thing. The problem is not the container, it's the H.265 encoded video which Firefox doesn't accept. It's not a good idea to throw raw cell phone video onto a website, first because it probably won't play everywhere, and second because there's embedded high-precision location data.
- sramsay64 2y agoIt's funny seeing this after the arguments in the mpv thread a few days ago[1] where over if VLC's extra bloat (and lack of features like stepping back a frame) is justified by it coping with diverse formats. This file doesn't play correctly for me in mpv[2], but does fine in VLC.

- calebm 2y agoThanks for the bug report.

- Karliss 2y agoI like how you chose the content of drawing so that it's complemented by lenticular effect instead of fighting against it. In many typical lenticular pictures that attempt to show an animation or 3d effect, there are angles in which you partially see two images thus ruining the picture by making it look blurry/striped. Not sure if it looks equally good in real life, but at least in the videos of your art the color gradients seemed to produce much smoother transition, which doesn't break the picture even when you partially see two consecutive frames.
- calebm 2y agoYes, if you want to do good lenticular art, you want nice smooth transitions (on a pixel-by-pixel level).
- ljf 2y agoThese are amazing - I'd love to buy one, if you are selling your art. Though shipping to the UK and import tax would probably make this prohibitively expensive.
- calebm 2y agoI am selling. I can be contacted at caleb@gods.art. I'm really not sure how much shipping/tax would be to UK (never sold internationally).
- evan_ 2y agothose look great, you should post a Show HN about them. I'd be interested to know more about your process if you're comfortable sharing.
- MaximilianEmel 2y agoWon't this show the wrong glyph if you're looking at it from the wrong angle?
- JKCalhoun 2y agoI suspect short people and tall people will likely disagree about what time is shown.
- ralferoo 2y agoThis must be what people mean when they say they are short on time.
- borski 2y agoHonestly, that might be my favorite part
- gmiller123456 2y agoYou notice you're running late, so jump up, and now you're early.
- BeetleB 2y agoWell, time dilation and length contraction do occur at relativistic speeds :-)
- o11c 2y agoHm, could that be fixed by covering it with a "privacy screen" (used to cover computer screens, basically a bunch of tiny parallel tubes (all-angle) or grooves (one-axis, probably best for this))? Then maybe a blur on top of that to increase the viewing angle again (though that might cut the light too much since it's not an active emitter)?
- augusto-moura 2y agoMaybe a pinhole and lens? Like a camera but having only the clock inside a chamber
- Someone 2y agoUtterly impractical as a clock. Brilliant hack. I guess version two will add a camera, an eye detector and two servos to orient the clock to create a real-live hybrid of xclock and xeyes.
- drjasonharrison 2y agogiven that the display is viewpoint dependent, you need to orient this clock to make it usable from a variety of vertical viewing angles
- eru 2y agoThe old Google badges used to have lenticular images, too. (Perhaps they still do? I haven't been working there in a while.)
- shibbidybop 2y agoThey were swapped out earlier this year for boring flat-image badges. Major bummer.
- eru 2y agoHah, that will make tail-gating behind a Googler by just flashing my old badge so much harder.
- dr_kiszonka 2y agoLenticular postcards were relatively popular in the 60s and 70s (iirc). A family member brought some from Japan and I was fascinated by them. Sadly, they got lost over the years :-(
- 082349872349872 2y agoA friend had a special lenticular camera, but that was ca. 1990 and he had to send the film away to get lenticular cards back, so even if you can find a camera, you may have to reverse engineer the printing/mounting process.
- sdflhasjd 2y agoI had some success making lenticular sheets using a 3d printer by printing a single-walled cylinder using a clear PETG, cutting it up and flattening it out using a heat gun. You can use the layer height to control "LPI". One problem is that it's double-sided, which reduces the quality quite a bit.
- mhb 2y agoAlso, one of many digital sundials: http://www.mojoptix.com/2015/10/25/mojoptix-001-digital-sundial/ http://www.mojoptix.com/2015/10/25/mojoptix-001-digital-sund...
- illwrks 2y agoVery clever idea. I wonder if instead of a printed sheet if you could combine it with an e-paper display with an interlaced image and then you could load different image sequences...
- drjasonharrison 2y agoClever in the "nice job, but this is not a problem I have, nor a solution I would want to have to listen to..." - you could use an e-paper display without the stepper motors - you could use an o-led display and be able to read it in the dark - etc
- illwrks 2y agoSorry I wasn't clear, I had meant clever in the same way you had outlined. To explain my epaper comment, I've seen several small keyrings and phonecase-type epaper screens start appearing. You could combine a small lenticular screen with one of these to have an updatable animated image. A pure novelty for kids/big kids - a complete waste of resources for nonsense though...
