There's a couple of new ideas on the voting page that are moving pretty quickly, and I think it would be a shame if people didn't see them because you only look for new ideas at the bottom of the list.
I posted "Confused Triggers" a few days ago, which makes all your triggers self-triggerable, but leads you to get confused and always say the wrong one.
There's also one called "Wet Age Regression" which is an interesting variation on the idea of age regression ... not sure if I'd try it or not, but its certainly original. The unusual trigger could possibly make it more effective, I think, as I can easily imagine your subconscious responding to actions more easily than words.
