I guess you were trying to be sarcastic by recommending IE :) IE 8 can only show the window title "Maestro Logo" and a blank white screen. Firefox 6 and Opera 11 can show the logo properly while Chrome 20 cannot show properly the intersection of blue and red circles.

The usage of canvas and JS is well done though.
