if you own a mac, then go and download these two:
sidetrack is definitely a must! i never thought i’d miss these features until i installed this nifty piece of software. sidetrack is a replacement driver for your trackpad on the mac. it enables scrolling features i now heavily rely on (it almost makes my mouse obsolete…). you now get a defined zone on your trackpad in which you can scroll the screen (preferably the left part for vertical and the top part for horizontal scrolling…)
collage is a funny little plugin for itunes which displays freely available images from the internet as a visualisation. it’s quite hard to explain, just give it a go.
ah, and most important: both pieces are freeware.
