TheMillionEtherHomepage.com is just one of possible representations of the contract sitting in the blockchain. As the contract code is open anybody can develop a representation of their own.
Here are few ideas:
- Bitcoin gateway
- Users tree visualization
- Sign in by email
- Ads stream instead of 1000x1000 px field
- Lending pixels
- Exchange (landlord contacts and pixel prices)
All contract information is readable through public functions and events. Please see the contract for details.
