Character Hunt at the Temple?

Wat Pariwat, located about 30 minutes by car from central Bangkok, is an interesting spot where you can find various characters scattered around what appears to be an ordinary temple. There is no entrance fee. It's hard to imagine something like this being created in a temple in Japan, lol. I visited in the morning during the dry season in December, and there were no other tourists besides me. Local people were praying in what seemed to be the main hall. Why not visit and try finding the characters yourself?
