Thanks for the kudos.

The hidden wires were the first design consideration. I still have 4 children at home under 8 (and a 17YO too the oldest (23) is married and has made me a grandpa).

As for the neatness, I always pick up my playthings and so... My wife says that does not quite match the whole creative thing (I'm a contradiction). She's grateful though.

@Mac: anytime.
