Some nice mock-ups there. One of the things that I enjoy about the PrimeDice experience is the simplicity and accessibility. There is virtually no barrier to entry, aside from the legal aspects, which means that somebody can go from loading up the website for the first instance and rolling for free (using the faucet) within a minute.
I've not used any of the other coin dice sites, but I'm really excited to see PD3, especially knowing how powerful JQuery is.
