I made this demo using http://www.pixijs.com/ Something I'm really happy with is the psuedo-3d effect on the cat using a displacement map. I took the cat sprite ( http://dn.ht/picklecat/mesmercat.png ) and made a "depth map" ( http://dn.ht/picklecat/mesmercatdisplacement.jpg ) where white is closest and black is furthest. This information is used to determine how far to move the underlying pixels. It's enough to give…

Well, I know what I'm doing for the rest of the day.

(if it wasn't obvious, playing around with pixijs!)

For everyone wondering "What's the music in the background?" It's here: https://www.youtube.com/watch?v=UsMewmMTA_c cleverly linked to via an autoplaying, hidden embedded iframe in the page.

The whole album is pretty fantastic: https://lazerhawk.bandcamp.com/album/redline

Great work, silly but ingenious. For some reason I find the "depth map" creepy to look at on its own.

Seemed silly at first (well, still does, but in a good way). But from the comments in this thread, I realized this is actually a pretty cool demo.

Completely unrelated to WebGL, but you might want to have the music loop forever or use a long playlist. That'd be neat - I have it open in background because the music is really sweet.

Earlier quoted context omitted.

I'm glad you asked! :) I created it in Adobe Illustrator using a gradient mesh: http://i.imgur.com/kuuFVO2.png Illustrator's gradient mesh tool lets you create a grid of points where you can choose a colour for each point. I overlayed the grid onto the sprite and estimated the distance at each point.

Is that something one can do with Inkscape as well ?

Nope, wonder how much it would cost to get it implemented?
