Arcing Prisms can do so much more than a little wiggle, but definitely gets wiggly if you want it to in the tamer settings on the pedal. For a little wiggle, I'd recommend any of the more modern lofi delays that seem to be released every other day. I've been using an EAE Hypersleep for this and loving it. The hypersleep is out of print now, but there are a bunch of lofi things out there from pladask electrisk or even midfi electronics among others.
