how to create a sketch with transparent canvas?
May I ask if there's a way to create a sketch with transparent canvas?
Like the following one (but it's using HTML trick): http://www.openprocessing.org/sketch/74380

I've searched for the very same thing about a year ago, and haven't found anything. This is a Java example: http://docs.oracle.com/javase/tutorial/uiswing/misc/trans_shaped_windows.html, but because Processing doesn't match all capabilities of Java, and a transparent/translucent background being one of those features, Processing can't display a transparent sketch.
There are several threads about this problem in the old forum... One solution is to open a new window with the translucency capability.
