One of the things I like about the Mac, is the ability to add widgets. Something I found myself doing frequently while working on Tomorrow is Forever, was figuring out how best to sync up the visuals with the music. I ended up writing down all of the BPMs for the songs, then taking the frame rate, and figuring out how many beats there were per minute. With late nights in the lab and long hours on the project, my math started to get pretty bad. This helped.
