Square Town

A live, 3D favicon wall. Every 1×1 square is free to claim; paste a URL and an email and Square Town fetches the favicon. Any square can be evicted for double its last price ($1 minimum); the 4×4 Throne in the centre starts at $100 and doubles on every eviction; the wall unlocks a new ring every time it is 75% full, up to 1024×1024.
