I'm not a fan of overhead projection but those pics look superb!
What were the powers?
The blue's were 5Watt 445nm, and the center was a 6Watt RGB, and when the power supply for one of the 5watt blues went tits up half way through the show, I grabbed my backup 5Watt Green and put it in it's place... It always pays to have a spare on hand...
