Considering that your system, power supply, storage and connection won't be redundant, I would not recommend this if you want the website to have decent uptime. The cost of a Pi would likely also pay for a decent low-end VPS for a year

Thanks to a very helpful contributor on Github, there's now a download link.

I've done something similar in another project (avatar generator based on username). That code would always use a seed, and generate a new one when none was supplied. The main issue I see is that all the non-random numbers in the code

Thank you. I tried to implement this, but I got empty/missing images on mobile browsers. It basically worked everywhere where right-clicking also worked. I'll look into it more when I have more time.

This wallpaper generator was written on a Raspberry Pi running Ubuntu. Which I use because of its highly convenient desktop experience ;).

Almost infinitely small. There are many random values used to create the image, and most of those have millions of possible values.

My bad. Seems that a number of browsers block saving canvas elements as a security precaution. For now, I can only recommend trying a different browser as a workaround.

Completely random. It picks a hue value (0-360) and then adds or subtracts a second random value from this for each layer. The maximum value of this increment is relatively small, so the colors are usually similar within the same image.

Unfortunately, no. There seems to be some issue with saving canvas elements as PNG on mobile browsers. Since the generated images are landscape aspect anyway, I didn't spend a lot of time figuring out exactly what's causing this.

This unfortunately, is a known issue. I tried adding a download button, but that also only worked on desktop. Probably some browser policy thing. The same is true for Android (Chrome and Firefox Nightly).

Thank you. Those are great suggestions, but I also like the simplicity of it being completely random. Perhaps I'll do an interactive wallpaper designer at some point, where you're more in control.

The width and height can be changed in the code. If you also increase the number of layers (vertical) and line segments (horizontal) accordingly, you should be able to get similar results at different resolutions/aspects.

I created a little web page (<10kB) that generates a random 4K (3840*2160px) wallpaper image using Javascript and the <canvas> element. Right-click to save the image (desktop only for now). No two images are the same. You may need
