Here is mine:
Entertainment Center Wire Apocalypse by

I've got lots of stuff hooked up, and almost no room to get back and mess with it!
PS2/XBOX
Pioneer CLD-A100 LaserActive Laserdisc Player
SNES/N64/NES
PC Engine Duo-RX
Dreamcast/Saturn
Model 1 Genesis + Model 2 Sega CD and a 32X. I've also got a Power Base Converter stuck in with my controllers for when I get that SMS itch.
Everything is set up pretty easy to use and I have a pair of Sony composite switches to handle most stuff, plus the TV does S-vid and component but I use the remote to access those. But ugh, looks like I need to dust a bit near the switches.
