In the past few years, we have covered plenty of cool plasma toys here. The Heartlite is also worth a look. It is a heart shaped plasma picture frame with lightning effect to make your favorite photo stand up. It can also be used as a science toy to light up neon sticks, plasma glass, and everything in between.
The Can You Imagine heart plasma photo frame is not easy to find but once in a while, it pops up on eBay.
