While at SDCC, I ran into a guy wearing the coolest 8-bit sunglasses. He bought them on Ebay, because the only ones available new were extremely expensive. ThinkGeek must have overheard us chatting, because now they have awesome and affordable 8-bit sunglasses for us all!
At only $7.99 a pair, I can see some fantastic group photo shoots coming from these. Available at ThinkGeek.com.
