Thanx atanere and rstanley!
This is not logo for SFS or Linux Kernel, they have their logo and MASCOT.
I've had two reasons for creating LOGO for linux - gnu/linux... I had to made Linux sticker for keyboard button (instead Windows logo and Apple logo) and I realize that Tux is too unreadable when resized to small dimensions. Then I start to read about linux hystory and found "GNU/Linux naming controversy"... It bacame my second reason - to make logo that will satisfy both sides...
I know that this not change use of Tux but when I make sketch of this idea I could not resisted the need to put this logo to the public...
