Well, the music isn't mine (see YT comment section for details) and i only imported some existing graphical demos and adapted them to use my imagecat routines.

Plus doing a lot of fiddling with the timing to make it work with the music. Ye olde SDL library didn't allow me to skip the parts properly i've already timed, so i resorted to using the stopwatch function of my wristwatch and the old pen&paper method of calculating the correct lengths for all the different parts. Talk about old school ;-)
