Hope you're talking about Diamonds there, Zeit has been pure PoS for yonks.

If you want to put your rigs to good summertime use I'd suggest Myriad on myr-gr algo or if you're feeling adventurous, merged-mining on Blake-256.

For those 'behind the kerb' mining one pool will give you four coins - Blake, Photon, BlakeBitCoin & Dirac - with at least 3 more to be added soon.
