If you were a Windows user back in the old days then chances are you'll remember a drawing program called Paint, which came bundled with the OS. Although it was hardly the most sophisticated design tool around, the program was great for children to teach them about the basics of digital drawing. The Mac community has already had a few programs of this type, such as the now defunct MacPaint. Paintbrush adds very little new to the genre and is pretty much a straight rip-off of MS Paint. That said, it's primitive tools are great for producing smiley faces and houses in seconds, and it is fun to play around with if you're feeling nostalgic. The fact that the program supports a range of different formats means it's good for quickly creating and sharing pictures.
