I recently got a DIY ambilight kit from Adafruit (adafruit.com/products/461 ), and was looking for a way to put the LEDs behind my monitor.
The way it is done in the tutorial, where they are mounted on a plate behind the screen, is not an option for me, since the VESA mount is used, and it is not possible to add an extra plate without extending the monitor almost 5 cm more out from the wall.
Instead I designed this led holder.
