As a hobbyist who enjoys programming, my interests are heavily biased towards "innovations" that make programming itself more interesting / enjoyable / satisfying, and less boring / mundane / repetitive. So, I especially like the visual/modular programming interfaces found in Max/MSP, Reaktor, Reason, and also in the software I'm currently writing called "Salvation" (http://www.slvtn.com) .
