Light Baffles

A generic "light baffle" box to allow air to circulate, but keep light from shining through. Very much in the testing stage. I'm in the process of building a case for a Linksys Ethernet switch I need in my bedroom, but I don't appreciate the gazillion flashing lights shining out of every side. The hope is that larger versions of these baffles will let enough air in to keep the switch from overheating.

I have constructed my Ethernet switch box, full story at: http://tomhorsley.com/hardware/s
