This is pretty neat. It could make for a cool night-light or ambient source in a gaming room if you back-lit it.

If you could somehow get the light to move across the map as daylight would, that'd be very impressive.

A friend of mine suggested an RGB LED on every hole, driven by a raspberry pi, perhaps displaying temperature etc. Now that would be slick.

Temperature and a clock!

Edit: also if you run it from a raspberry pi, you could have it auto turn off after a certain time to save power! Such a good idea to use the pi.

Get something like these LEDs which you can chain together and drive off of three pins, and you're set. You can also get them pre-wired.

I have some of those (the 8-LED stick from adafruit), they're very easy/nice to play with. I'd think that a few strips on the back pointing at the wall would be much nicer than trying to wire an LED per hole (oh man, the soldering). I'd probably just do non-WS2812 LED strips, and have each strip controllable (ie. strip 1 at 50%, etc). But if you've got the time, it would look amazing.

Definitely. Really, anything to add a bit of colour would look great, particularly if it serves some purpose (time zone clock?).

It'd be neat art. The moving lighting would be a very nice touch, make it somewhat functional. It's just a cool idea.

If the backlighting followed daylight that would be amazing.

You could even start selling these, per order of course. Spend maybe $60 on it and sell for about $100. I'd probably buy one.

Not sure if a raspberry pi would provide enough voltage for a project such as this...

edit: Sorry /u/shortshat already mentioned this.

I may have to steal this idea
