Tetris - 1.0

Thanks to all for good replies.
I will try to take into account all of your propositions and observations to make the next version of the game better.

Very fun! Although it should probably progress a little faster.
You should probably consider adding a caption and icon. Code could go like this:
pygame.display.set_icon(load_image('icon.bmp'))
pygame.display.set_caption('Tetris')
And you'll have to define a load_image function.

Also, I miss those ghost pieces that show you where the block would land if you dropped it right then. Those really help!

Don't be scared to try out all of pygame's stuff. Alpha values, image loading, music, all that cool stuff!

Very cool! The blocks move down to slow though...
