You can’t really see them in this size, but if you click on the image below you will be able to see the LED lights just below the green and red buttons.

Stuff I still need to do:

Get the marquee printed at Kinko’s.
Get glass to server as bezel in front of the TV.
Design artwork for side of cabinet, front of drawer and glass bezel.
Install piece of trim across the front above the drawer.
Get glass to server as bezel in front of the TV.
Get a switch box so I can install an XBox 360 and PS2 and switch between them.
Make an opening on the front door to give easy access to consoles etc. inside.
Whatever else pops into my head! :)
