Aqua-Soft ForumsI composed this several months ago, it's not a song or anything, it's just an exercise I do before I play to warm up and get my fingers in shape. I find it very useful (like any other chromatic exercise -try Peturcci's version of a Chopin piano song too-). My exercise is not based on the chromatic scale, it's just several chromatic measures.
Anyway here you go grab it here 
Hope you guys find it useful.
