Guile 100 #7: Animated GIFs

Challenge #7 in the Guile 100 Programs Project is to write a function that creates an animated GIF from a datacube of 8-bit color indices and a 256 color palette.   It is the third challenge in this month's theme, which is "Web 1.0 -- Web 1990s style".

The Guile 100 Programs Project is an attempt to collaboratively generate a set of examples of how to use the GNU Guile implementation of Scheme.

There is a 100 USD bounty for writing a readable solution to one of the problems.  Anyone can fork the repo and tell me to pull it or just send me a solution by e-mail at guile100 [at] lonelycactus.com

Three other problems remain open.

• Challenge #5: PHP-style Guile
• Challenge #6: CGI and MySQL

This week I received solutions to

• Challenge #3: LZW Compression
• Challenge #4: Tar archives 

There's one more problem left in Web 1.0.  Probably something to do with Gopher.  See you next week!
