I made a completely new (mathematically and sonically) modulation effect called Poltergeist. Capable of all sorts of wild (or subtle) sounds - I personally love it on guitar, drums, and as a drop-in replacement for reverb, but friends and early users have really surprised me with what they've been able to do with it. Definitely made for the adventurous!
