As I'm working on cleaning up a pencil drawing in Photoshop, I'm reminded of what a great device the Logitech NuLooq is. I wrote about this a while ago on another blog, but I've been using it more lately, and really loving it.
Basically, it let's me monkey with all the important settings in Photoshop with my left hand, while my right hand is holding the stylus for my Wacom tablet. This feels a lot more like working with real art tools, and not having to type keyboard commands. With my left hand, I can make the brush larger or smaller, zoom in and out, and scroll anywhere in the image, even while zoomed. I could add a few more functions, but I haven't figured out what I want yet. I can almost put away the keyboard while using Photoshop (except that I'm on a MacBook Pro!)
There are some other interesting specialty input devices, such as the ShuttleXpress and Logitech's own Space Navigator 3D Mouse, but these don't seem as well suited for graphic arts.
Unfortunately, I don't seem to be able to access any NuLooq pages on the Logitech site today, but it's still available through Amazon.com and elsewhere.
