Very cool and stylish!

I made a modification - added colors:

Awfull! But the colors are too nice to represent dirty pollution. On my machine mc is set back to 0.4

Well, I thought that with darkening by shadow, bright colors will look quite appealing

Yes, I agree. "Awfull" was the wrong word (English not beiing my mother language).
The 3D shadow and the collors are a big improvement.

By the way, is there any means to check on which hardware an SB program is running? Could an SB statement for that purpose be possible?

[Mr. Kibernetik]

New version. Transparency added for more subtle color effect.

Yes, it is a good idea to make hardware identification...
