I picked op the Tenyo version of Scotty York's Lamp Trick last week - actually my first Tenyo tick. It's well made and I would guess actually more robust the the versions sold by Ken and Paul, although there's no obvious way to change the bulb.I originally used Beam Shot and then the original of this trick for years. I had mechanical failure with both eventually and then they just faded into disuse.
When I got the new version, I played with it a lot. I'd forgotten what a cool trick it is. The more I worked on it though, I wondered if it will play in 2011. It seems it can easily be explained as "electronics" and there goes the mystery.
