Luckycoin - random blocks
Novacoin - scrypt/pos hybrid
Cosmoscoin - novacoin/florin hybrid. Zero transaction fees.
PHS - novacoin/florin/luckycoin hybrid. With 50% POS per annum.
YAC - Scrypt-jane . modified scrypt algo
I don't see a lot of innovation in these:
Luckycoin - fancy block rewards
Novacoin - previous stuff hybrid
Cosmoscoin - previous stuff hybrid, small parameter change
PHS - previous stuff hybrid, small parameter change
YAC - This was a little more innovative because it was the first coin to experiment with high memory requirements. Still only parameter changes?

Also coins on the list must have been publicly launched. Code should be public so claims can be verified. Will add these additional requirements to the OP.
Surprised this made the list for that.

Can't find anything on it. Wonder how that was supposed to work

Ixcoin isn't dead, I guess.
It's traded at Cryptsy and it's merge mined

Thanks. It's a zombie.

SC still processes transactions and is traded as well on mcxnow.
Another one.
