Plasq.com has released Comic Life 1.0 for Mac OS X, an application that lets users add comic book-style embellishments to their digital photos. You can add simple captions to your photos or even use them to create full-fledged comic books, according to the developer. A demo download is available, and the full version cost US$39.95 to register. more
It looks like a fun program. If it were a bit cheaper ($20-$25?), it would qualify as an impulse purchase-worthy for many people, IMHO. But at $40, it makes one think twice about "do I really need this?" It made me think twice, that's for sure.
I just played with this thing for the last half an hour. It's actually extremely cool. The interface is easy and intuitive, the sound effects are kind of fun, and it taps right into your iPhoto folder. Like all the best creative tools on the Mac, the software gets out of the way and lets you work.
