In fact, let's make today a two-fer. To celebrate the frost I'll provide two photos. I think this next one is very Zen-like. Natural materials in a simple, regular design with a touch of irregularity. No big rocks, no human intervention, but a soothing image that reminds me of the dry gardens of Japan.
This is a simple photo from our back deck that covers a space roughly a foot square (roughly 30 cm by 30 cm). The stone is a natural river stone from Mexico, displaced from its usual place of repose in the garden by forces unknown.
