We are taking a very hard look at SHA-3 Keccak.
SHA stands for "Secure Hashing Algorithm" and is set by the National Institute of Standards and Technology (NIST).
http://en.wikipedia.org/wiki/Secure_Hash_AlgorithmSHA-0 Has been exploited.
SHA-1 Has been exploited.
SHA-2 What Bitcoin uses & most cryptos.
SHA-3 Next generation super secure hash. Maxcoin implemented SHA-3 Keccak
We have been researching much more into Keccak.
http://keccak.noekeon.org/http://en.wikipedia.org/wiki/SHA-3What really caught our attention:
Keccak excels in hardware performance, with speed/area trade-offs, and outperforms SHA-2 by an order of magnitude.
Keccak has overall good software performance. It is faster than SHA-2 on modern PCs and shines when used in a mode exploiting parallelism.
Rumor has it a GPU miner for Keccak has already been developed. We are thinking we can modify Keccak for GPUs.
Yes, Keccak algo can be mined using Cudaminer (Nvidia Users), the following is a test with a GTX660 without overclock using stable cudaminer's settings to this videocard, this example is with Maxcoin:

About temps: with current Scrypt algo, this videocard is close to 68 C , with Keccak is stable in 45C
In this thread has more info about cpu miner and gpu mining with AMD videocard :
