I DID IT! I DID IT! w00t! w00t! w00t! I FREAKIN DID IT! I completed the template for LEVEL 4 of the game! I took the Spectral peak closest to 9hz (the heart brain harmonic connection?)to .60vrms (the distance between the bottom and top of the wave) 46 TIMES! All ya need is a scoring system and some flashing graphics when points are earned. Add a server and folks would be able to play it interactively over the internet.
