There are more but these are the apps I've made in the past month or two. I've tried to experiment with a variety of viral techniques and range my projects from local to universal context. The only one that got any notable traffic was Mugshot Wars, but it's tapered off to a few visits a day now.
They seem like decent enough projects for fun. But anything long term might be slightly tricky. I particularly liked memify.me and it seems like it could catch on. leftright, as someone had pointed out, seems similar to what's been done. An extension of leftright could be including some sort of question for people to guess - could be age, location, etc.
