  My friend and I write a physics/art/geometry/math blog with gifs for illustrations: http://danielwalsh.tumblr.com/ http://danielwalsh.tumblr.com/ - denser posts, but hopefully fun. (Here's also a list of posts, since they're so long that the blog can be hard to browse: http://danielwalsh.tumblr.com/tableofcontents http://danielwalsh.tumblr.com/tableofcontents ) I also recommend http://blog.matthen.com/ http://blog.matthen.com/ (tons of math gifs with source code) and http://visualizingmath.tumblr.com/ http://visualizingmath.tumblr.com/ (lots of gifs and other images along these lines).

  Inspired by that post[1] on Go a few days ago, I made a few animated parametric plots: http://i.imgur.com/gUm1T5S.gif http://i.imgur.com/gUm1T5S.gif http://i.imgur.com/xR5uqle.gif http://i.imgur.com/xR5uqle.gif http://i.imgur.com/SVvuRII.gif http://i.imgur.com/SVvuRII.gif [1]: http://www.pheelicks.com/2013/10/intro-to-images-in-go-part-1/ http://www.pheelicks.com/2013/10/intro-to-images-in-go-part-...

  This was exactly how I made sprite animations back in my Amiga demo coding days. Take a look at early C64/Amiga demos and you'll recognize these patters.

  My personal favourite mathematical animation is the construction of Bezier curves: http://en.wikipedia.org/wiki/Bezier_curve#Constructing_B.C3.A9zier_curves http://en.wikipedia.org/wiki/Bezier_curve#Constructing_B.C3....

Ah Mathematica: $ curl -s http://4.bp.blogspot.com/-MPv_CwvvwKQ/Ulrw3TfdgyI/AAAAAAAAAEw/YsRPmU6C5xM/s1600/trefoil_rotate_white.gif |strings|grep -i created UCreated by Wolfram Mathematica 9.0 for Students - Personal Use Only : www.wolfram.com Would love to see the source for them.

  Upvote for teaching me the "strings" command :) Never heard of that one before! Seems really useful.

    If you're wanting metadata, consider exiftool also: $ curl -s http://4.bp.blogspot.com/-MPv_CwvvwKQ/Ulrw3TfdgyI/AAAAAAAAAEw/YsRPmU6C5xM/s1600/trefoil_rotate_white.gif | exiftool - Output contains: Comment : Created by Wolfram Mathematica 9.0 for Students - Personal Use Only : www.wolfram.com

That simple parabolic reflection animation explained the concept more elegantly than words ever could, I think.
rohitv 13y ago
Interesting, but I still have a headache since I looked at the gifs about an hour ago. Maybe it's just me but I would advice putting a warning somewhere.
B-Con 13y ago
When I opened the first page I thought that it would be a page of unrelated GIFs. I saw the first one, read the accompanying paragraph, and stopped to think about it. I thought for a while before proceeding on, at which point I noticed that I had just thought through the next several GIFs of explanation. That's why math is fun. You can always participate in the analysis.
XaspR8d 13y ago
Excellent! I'll have to spend a while exploring the archives. I just happened to have "proved" to myself the linearity of a very similar animation a few weeks ago. :) http://i.imgur.com/fxHj3kZ.gif http://i.imgur.com/fxHj3kZ.gif

Many similar GIFs to be found on Giphy: http://giphy.com/tags/geometry/ http://giphy.com/tags/geometry/ http://giphy.com/tags/math/ http://giphy.com/tags/math/ http://giphy.com/tags/physics/ http://giphy.com/tags/physics/
icambron 13y ago
These are really neat, but one thing I don't understand is the animation they linked to (i.e. the post that inspired the OP) [1]. Unlike the animations in mathgifs, my brain isn't interpreting anything there as rotational motion. Am I missing something? [1] http://beautyandthemaths.tumblr.com/post/62281036101/the-average-gatsby-there-is-zero-rotational http://beautyandthemaths.tumblr.com/post/62281036101/the-ave...
- mythealias 13y ago
  That was the same with me. I guess it is because the dots are already colored, thus leading one's focus towards the translation. However if you ignore the colors and imagine a 3-petal flower, then you can see the flowers rotate counter-clockwise. Try following the outer edges where the density of dots is sparse and less confusing to form a mental image of the petal.

  Zoom out
  - icambron 13y ago
    Tried that-- didn't seem to help.
- laumars 13y ago
  The dots are further spaced apart so so your eyes are drawn towards individual balls rather than the image as a whole. Plus as the balls are already coloured and you have ball tails, it's easier to see the ball paths. Also, worth mentioning is the balls on this follow a subtly different path as they don't intersect the centre of the shape like they do in the article's gif.
philbarr 13y ago
Anyone know a good place to plot the mathematical envolope at the bottom of the page? But like, quite big? I know it might seem a little facile but a nice plot like that would look pretty cool on my website. :)
