The marbled D12 certainly looks cool, but from what I can see the others look fairly plain. The D10 always seemed a rarer version but as an old Rolemaster gamesmaster I tended to get them in pairs.
IIRC my marbled die are both D10s, while the rest are also pretty plain (or customized) - they've not seen the light of day for years.
I'd never considered them as a photo subject, they do work well so perhaps I'll give it a go.
The kids are now old enough to enjoy FRP if I can get them off the computer games for long enough - that could be worth a try too...
