I don't have a site from which I can upload, but I can detail how I just created some pretty cool looking foam.

Now granted, this "foam" sits on top of a pint glass, and looks as though the glass is about a couple of feet away from the viewer.

Perhaps some of you can try this out to see what type of results you get. Here is what I did:

1. I used the freehand tool to draw a foam-head shape that covers just over the top of the pint glass and about an inch down into the glass.

2. I used a flat fill, and borrowed RUSS-USSR's foam fill color of RGB (190,191,175).

3. I then applied an elliptical transparency and fiddled with it until I got a nice looking highlight.

4. I then cloned the shape and applied a gravel(1) fill from Xara's Ground fill gallery for some texture.

5. Lastly, I applied a flat, mix transparency to the gravel fill, set at 93%.

It looks pretty convincing for an image that's not too close. As for applying foam to an image that's upclose...I got nada!
