Great idea poorly executed. Definitely not worth the price. Looks clunky, animates jerkily at any size above tiny. Preferences bizarre - far too many "features" - and changes to them seem to have only limited effect. I set it to take pictures from my iPhoto library's 2005 sub-folder, and it repeatedly chose pictures next to each other in sequence, so I got six versions of the same scene. Locked up for a few seconds every time I changed the preferences and sometimes for no obvious reason at all.
