First, it's a really weird experiment. The whole idea is to have a text/programming-based sprite format that compiles directly into the binary blobs used by mode-lambda. Given that sprites all very small, I find it more of a burden than useful to use an traditional graphics editor. So, apse does stuff like showing you an animation at different scales and in different palettes while you are making the sprite.
There's an example in Get Bonus: https://github.com/get-bonus/get-bonus/blob/master/gb/art.rkt (You don't need any other files from get-bonus, so you can just use that if you want.) Then you run apse on it: racket -l apse/tool -- ../get-bonus/gb/art.rkt And a window will pop up showing the image (based on the last expression in the apse submodule.) The cool(?) part is that when you change the file (i.e. save) then apse will reload it and you'll see the change. Occasionally there's a runtime error and you need to restart. Bummer. Most of the examples in the art file are in a 16 color palette with 3 major colors (A, B, & C) and 4 highlights. They are encoding with single characters. _ is transparent, $ is black, ! is white, then qwe are the tints of ABC, asd are the bases of ABC, and zxc are the shades of ABC. The highlights are fghj. I recommend using emac's overwrite or artist-mode.
