Facebook Apps

Anyone know where to get free facebook apps or examples that work? I fount 1 in the download section and working on a retweek and release but need more ideas. So if anyone has any apps dealing with photos or of the such please let me know

Before you waste to much time with apps you find online that are free, make sure they are recent apps. Things have changed a lot over the last year and things will be changing more in the coming months, so no reason to spend time on an app that wont work.

well then if anyone has any recent app ideas on photos i can upload but having tagging problems and been reading the dev forums and searching but just can't figure this **** out
