Mac Developer Cam Stevenson dropped us a note to let us know that BurrOak Software is looking for beta testers
try out PictoDrop. PictoDrop is an image management program that looks like it will help you sort, version, and apply effects to your images in a very Aperture-lite post-processing way. It's a closed beta, so if you're interested you're going to need to send off an e-mail to firstname.lastname@example.org
to apply to be a tester.
It looks like a fairly cool program, built at least partially using Core Image.
