These are 2 MV I just made... well, strictly speaking they are not music videos lol
They are basically some kind of randomly generated visual effects on your desktop which respond to music in real time.
I did similar things with Kannagi and other Anime before, but this time the effect and style is quite different. Personally I am quite satisfied with the randomness and simplicity (using mainly still pics as background instead of animated frames) of this effect I created.
By the way... can you find the hidden words inside the Matrix rain? Consider it a game... XD
