During the Mark Elsdon At The Table lecture he used a 4 piece plastic puzzle during an effect.

Does anyone know the name and manufacturer of this puzzle?

Thank you.....

I haven't seen the lecture, and there are a lot of 4-piece puzzles, but would it be Instant Insanity?

Thinkfun makes a few interesting 4-piece puzzles: http://www.thinkfun.com/results?search=brainteaser

If not, you might find it in this graphical puzzle index: http://www.jaapsch.net/puzzles/indxgraf.htm

Hey Scott...

You got it. It's the 4-piece jigsaw by Think Fun

Mark Elsdon does a challenge where he solves a mixed Rubiks Cube explaining the 43 Quintillion odds and has the spec try to assemble the 4-piece jigsaw puzzle. Of course he gets there first every time.

Just purchased 2 of these, I'm puzzled why?
