NIME Inspiration

I've been looking (and listening) online for some NIME music that I find inspiring when I think about making my own instrument. I've found that I'm really not into a lot of the "techy" sounding music - I like guitars and pianos and such. On the LEMUR site, I found this recording, EmergencyBot.mp3, that I like better than anything else I've heard. I guess something I'm really going to struggle with is that I like the way traditional instruments sound, so I'm going to have a hard time creating something that I like better without a sense of purpose. Maybe I will end up doing something that I consider "assitive" as well if that's an option.
