Ninjinuity describes "an idea, invention or action that surpasses ingenuity in a sneaky way". This is possibly the most awesome portmanteau out there, and it ought to be part of the language. I plan to use this blog to ramble though my ideas; I am tired of losing my concept notebooks and the stuff within them. I shall post my better ideas here as a reference for myself. Feel free to follow along and comment on my work.
