This one is a bit of an experiment. UPDATE: Most of the moss you see here died. However, there were survivors... After conditions stabilised, plants slowly recolonised the terrarium as you can see in this update.

Marimo Terrarium. You can get Marimo moss balls from aquarium suppliers. An interesting natural phenomena, commercial marimo are not collected from the wild. Very easy to maintain, I just change the water and keep it in a cool & very shady spot. The Crab and Starfish are from a museum giftshop.

My Bottle Garden. These were very popular in the 60's through to the early 90's, but then fell out of fashion for a time. The lizard isn't real [obviously], it's another museum giftshop purchase.
