Digital Cruncher has released Keccak, and Tribus (1.95GH/s):
https://github.com/digitalcruncher/keccak-tribusSo now there are 3 algorithms available. I am working on 2 more for August (which ones are currently secret), and in August, Senseless releases Lyra2z, GPU Hoarder releases CN7 and Digital Cruncher has I think two more as well. So by August there should be about 9 algorithms available.
