CHESS BY KEMMLER - 1V1 DUEL OF WITS - NEED HELP WITH RULES!

This map was a random idea I thought up of during the night. Turning on my laptop and creating the basic board in GIMP I got this:

Half an hour later and some nice effects, I have Version 1:

If I say so myself, it looks pretty cool. I could fall asleep looking at those dreamy colours and numbers...
The boards basically set, I just need the special rules setup. The rules I created are crap, I need someone clever to think up of some simple rules (that'd fit in the legend) and make this fun.
Remember, it's a 1v1 dule of wits.
Thanks for reading, hope it interests you!

PS Someone else has probably started work on something to do with chess. This is separate and is not or will not be anything to do with the other chess board. If this has to remain the second project, it's called 'Dream Chess'.
