Doepfer

If you want some inspiration on a different direction for what to make  
synth hardware look like - check out the stuff done by Folktek:

Very cool looking "Steam-punk" like stuff done in old test instrument  
cases. Very creative. Functional stuff that looks like it came out of  
a lab in the 1800s. This is what is the coolest thing about analog -  
you can make controllers out of almost anythin that works like a  
switch or resistive element.
