Groovy Thresh?

Quick idea that popped into my head and I wrote it down, Groovy Thresh? It all seems to work so far, but a few more idea need some ironing out, and where better to get sound advice than from random strangers on the internet, right? Well, tell me what you all think, and hopefully rito sees too.
