I still use Online Dice whenever I want to show rolls to my group without us being together. The dice roller online keeps things simple and has that old-school vibe I like. Plus, being able to link the results is handy for keeping track or checking back on past rolls during longer games.
Somewhere way down the road, perhaps that mobile Holographic version will be available. Perhaps for the 50th. Anniversary of the 1980s GameMaster Series, thanks, Pellulo
