Rita is similar to Scribbles (and you may have read me boasting about Scribbles) for the Mac: it’s a vector drawing program featuring an infinite canvas. I love the infinite canvas.
Unlike Scribbles, Rita allows you to edit each individual brush stroke and, unless you merge them together, remembers each one (this bogs your machine down while zooming, rotating, etc. but is otherwise a zippy fast app). Rita also allows bitmap imports, so at some point I’m going to be using it to composite PNGs with nice alpha channels (Update: import is fine, alpha channels perfect, ability to rotate individual objects fail: the software will rotate but it resizes at the same time. Doh.)
I’m not sure why I chose green. But it did bring me down the garden path to the Joker’s place.
Get Rita. It’s free until you register and registration is only $20.
