One rackspace. I want all the flashing, colored LEDs and bars and meters and levels and stuff I can in that space. What are some rack components that I might not need all that much... but look REALLY cool and distract anyone with ADD easily when up on a stage. I'm not just talking about single-color red Korg tuners, either! Please help me out... I want to go completely pointless, yet neat looking! P.S. My favorite color is blue!
