A slew of new apps have been released as of late (no doubt due to the Apple Design Awards deadline) and Freeverse didn't want to be left out of the party. Periscope is a webcam utility that adds a bunch of cool features to your Mac's webcam (builtin or otherwise). You can set it to take a pic based on motion, noise, a timer, Applescript, or by pressing the Apple Remote. Once you have a pic, or a series of pics, you can upload them to Flickr, an FTP site, or export them (you can even create a time lapse movie).
Periscope is available now for $29.95.
