McPixel, a frivolous lisp hack.

Yesterday, I had the idea that it would be easy and entertaining to hack together a toy application for drawing and animating pixel art. Some hours later, McPixel was born. It provides an editable grid of pixels, a color palette, and allows you to string sequences of images together into animations. It's a toy, but someone might find it amusing. Obligatory screenshot:

• 80's retro McCLIM user interface.
• No documentation or online help.
• Maximally frustrating color sliders, using IHS colorspace.
• Intuitive modeless drawing UI, achieved by including only a pencil tool.
• Saves/loads files only in its own format, based on unportable s-expressions.
• Requires X11 and SBCL with threads, to keep out the riffraff.
• User-editable brush shape.
• Remap Color and Silhouette commands, for tracing previous frames.
• Realtime animated preview plays while you work.

I'm not sure I'll ever put this to productive use, if a productive use for such a thing even exists, but there you have it.

Update: I've added the ability to export an animated GIF file, using Xach Beane's Skippy library. Here's the "turtle.anim" example file, exported as a GIF:
