Unintentional Green: Green Trace

If you don't have much time to take care of plants but like green very much, Green Trace is a good choice. It is designed as a tablet with surface full of sieve holes, and some seeds are pre-placed inside. In rainy days, you can place your umbrella or shoes on it, and the rainwater will flow along the sieve holes into the bottom to promote germination of seeds. In a short while, the familiar green will return again. Meanwhile, it can also keep the room tidy, achieving two goals at once.
