Dr Sparkz Lab © 1992 Atari Games Corporation.
This game is a combination of Tetris and Pipe Dream, and is very similar to the 1993 Taito prototype arcade Cachat/Tube It, as well as the earlier Famicom game from 1991, Gorby no Pipeline Daisakusen. The player has to make connections, or sparkz from the red side to the blue side (or vice versa) so that the monster that the scientist is making could be built. The monster is made piece by piece, and the first piece made is the head after connecting 2 sparkz.

It's a very rare prototype, there are only 2 or 3 in existence. The concept was just a little too hard for a mass market. It would make a great game, but Atari never decided to do anything with it. Its earnings in an arcade test just weren't high enough to justify production.
