Thank you. I love the look of your floodlight wash.
As for the MP3 route, don't be afraid. It took me several different attempts of getting real music to play through this unit for it to work for me. But nothing ever goes easy for me. It's a 'curse' that my friends call the "Bob Factor":D
Last year I first attempted to use a portable cd player with a cd of the mp3s I wanted to use. At first the cd players wouldn't play the cd's. So I bought a different brand of blank cds and burned the mp3s to that. That worked. Then I had battery life issues witht he cd players. (I used 2 different cd players). After going through 2 pack of batteries every night, I scrapped the cd player idea. Next I decided to try the kids mp3 players. I had horrible results with those ranging from horrible sound quality to killing a AAA battery every 2 hours. So, I decided to try using a really old spare laptop that I had laying around. Using a small patch cord from the head phone jack of the laptop to the Aux jack of the Gemmy unit worked very well. Unfortunately, I had to leave the laptop outside.
This year I decided to use the laptop again but this time store it inside. I got a 25 foot patch cord to make this happen. The only downfall was the cord had to go out the door. This lasted about 10 days before either the 14 year old or 13 year old cut the cord with the door by not assuring the cable was on the bottom at the threshold instead of up in the door jamb. According to them, none of them did it but you know how kids are. So back to square one again, I decided to try an MP3 player once again. Fortunately, one of the rental properties I manage is a sort of pawn shop. I found a fairly decent player that recharged via a usb port. The housing on the player had a chip out of it on the corner and the shop owner gave it to me at his cost, $8. I brought it home, wiped the memory, charged it up, put my mp3 on it and tried it out. The battery lasted almost 5 hours and I was happy with the way the lights were flashing. The videos on my Vimeo page are a result of this current MP3 player.
As for next year. I'm hoping to go the LOR route. The wife said she was going to buy me a controller for Christmas but I asked her to wait until the Feb/Mar sale to save some money. I just hope nothing happens to take away that cash stash before the sale.
