The New Tetris is pretty much your run of the mill Tetris with some neat additions, which we'll get into another day. Today, we'll talk about an interesting little Easter Egg.

First, go to the Audio screen and change the Music Mode to Choose, and the Song to Haluci.

Then go to single player and pick 'New Name', and make your name 'HALUCI' (without quotes, of course)..

Press OK, and... The colors!

It'll swirl and pulsate to the music until you decide to reset the machine.
