The Artifex Mundi games have Hidden Objects and I'm surprised that I rather like them--though why I should be surprised I don't know, since I'm a fan of the I Spy books (which, come to think of it, probably have games, too ...). I've enjoyed Grim Legends and the Nightmares of the Deep ones especially. So sure, recommend away!

I've run across jayisgames and have yet to delve into it, but yeah, it looks handy!
