Small update: the results have been posted and out of a little over a 1000 entries we got second place in graphics, fifth for mood and seventh for audio 
Overall we ended 17th, which we’re also quite happy with.
@ : I agree, although sadly I haven’t been able to convince my rational side that I actually need one just yet…
@TAXI: I’m not sure what you mean, are you asking how we did the emissive crystals? If so, you are actually quite right that it’s a combination of an emmisive material and lights hidden inside to provide the actual lighting on the environment.
