My son bought one of the "new" ones last year. It plays several games, one in particular is very similar to Simon - has flashing lights and you follow the pattern by pushing the colored buttons on the bottom. We bought the "full set" during the 100 year celebration - he wore them all and they flashed like mad as we went through the different attractions. We didn't know if they would still work and he didn't want to wear the one that specifically was just for the "100 Years" when we went in 2003, but we did bring the park ones with. Last year he noticed the "new" pin and bought that and wore it instead. It did light up, but wasn't as showy as the others. He didn't wear the old ones so we weren't sure if they would still work or not - maybe we'll bring them down and try them out when we go (Saturday :sohappy: :sohappy: ) and, if, we do, I'll post something when we come back.
