glsnake has been dubbed a "hardware accelerated executive stress toy" by its fans. It merely provides a virtual Rubiks' Snake toy for the user to play with by rotating joints about; quite a lot of fun can be had by creating new shapes with this toy.
Read the fine manual page for usage instructions.

for example,
type
scons
to get this up and running.
