Electris
From Fybertech Wiki
Electris is a Tetris clone created by FyberOptic in 2002. It was his first attempt at a full game written for DirectX in C++, for which he not only programmed, but also rendered the graphics and created the music. Originally intended to be sold for a small fee, FyberOptic later realized that other Tetris clone producers had been sued by Tetris Inc., at which point he decided it simply wasn't worth the risk, and released the first version as freeware.
The game underwent a couple of point-release updates before Fyber lost interest in the project.
