If you can’t afford one of these fancy Cintiq tablets (i tried one out a siggraph a year or so ago and they are worth the $ if you got it to burn)-

maybe this new tool from Logitech will hold you over until you can!

Divided (like a pizza) into 8 cells that can be filled with tools, filters, commands, files or applications, tooldial allows you to quickly customize your workflow. Drag and drop your most frequently needed items onto the NuLOOQ console to build your own custom interface.

i am not sure what is with the really goofy names for these things…”NuLOOQ”??? but hey it ONLY works on the mac so buy one and snub your PeeCee based designer friends…as if they need more annoyance, they’re running windows!

Personally i own one of these griffin powermate dealies. it is cheaper than the others, but has less features. i like it as it works pretty well in Final Cut and audio apps likw Garageband as a scrubber…
