The concept looks great and I really look forward to seeing how the mesh turns out.
Cheers for the additional info on transparency Mark, will be incredibly handy. Do you know if i add the line myself will i be able to view the transparency in the stock standard publish new item window? (Edit: beat me to it Spudnik!)
