Cool that Adobe is doing a whole suite of Touch Apps, including Kuler and Ideas. Ideas always seemed like a cool minimal drawing app. This weekend I reinstalled it for something I needed to draw:

It took a few tries to figure out how to make the screens a consistent size. The easiest way to move around is to drag with two fingers, but if you pinch or stretch while you do, the zoom factor changes too. In the end, after drawing a few screens that were small enough to fit the whole map into the Ideas canvas, I picked one screen to standardize on. Whenever I needed to stamp out a new screen I would go to the standard room, zoom until it fit just right in the frame (the whole iPod screen), then use the Move tool to pan to the new location without affecting the zoom.

Turns out it's convenient that I just reinstalled it, since as part of Touch Apps it's now $6. (Maybe it's worth it.)
