Crypto Skulls

So, continuing my skull-based cryptocollectible theme from yesterday with Skullys, here we have Crypto Skulls.

CryptoSkulls are 10,000 collectible ERC-721 Non-Fungible Tokens stored on Ethereum blockchain

Each CryptoSkull character is a unique pixel art with Uniqueness Index property. This property shows total rareness of all image features. CryptoSkulls with rarer features have less Uniqueness Index. Check it!

Again, I don't super really get it. Basically someone has set up a blockchain that randomly assigns attributes to characteristics to the pixel art skull, and then flooded the market with a heap of skulls. Just not sure what value they have?
