Neos, or NeosCoin, is yet another digital currency of the Bitcoin-like variety. Its website notes "the overwhelming amount of new crypto currencies surfacing daily", and apparently reacts to this in a similar manner to this xkcd comic. They claim they're more focused on supporting their users than the others. Their tagline is "We didn't want it to be the same old round rolling wheel." (So is it a square wheel?)
One technical difference they claim is the use of multiple mining algorithms instead of just one of them.
