I've just discovered a medium of art previously unknown to me: aquascaping. That's landscaping inside aquariums. It's a highly competitive field. The International Aquatic Plants Layout Contest is an annual event where you can see the finest examples of aquascaping. The Grand Prize winner gets ¥1,000,000. That's about $9,560.
Some participants try to duplicate terrestrial environments--even deserts--under the sea. Others make full use of the water to create elaborate, delicate forms out of living plants. You can view more examples at Colossal.
