Um, I'm really sorry - I tried looking for it, but I think maybe they took it off the site because I just can't find it - no matter what key words I type. Doesn't the brush work? Because the brush is basically the same as the picture, and it should be a really large size as well.
Believe me, this does come in handy...i actually lost it somehow and went stircrazy trying to find it again, typing in the search for crowd, audience etc but to no avail and then it came to me 'mosh pit'!!! and there it was! I am so happy now [link]
