So far you can only visit Pandora in the movies, but Singapore's planned Marina South Gardens project will combine its own man-made and natural wonders — with lush, vertical gardens scaling gigantic artificial solar trees.

Singapore is currently developing its largest garden project ever, showcasing plants from various climates. Giant fake trees collect rainwater and solar energy to power the conservatory, with vertical gardens climbing up their stems. The garden will feature separate biomes for different kinds of plants — a cool, moist biome for plants from the cloud forest and a cool, dry biome for Mediterranean plants. The first phase of the project will be completed in 2011.

Now, if only they could find biolumiscent plants to light the way in addition to the artificial lights from those solar trees.
