Have you ever felt like playing God -- shaping continents, creating rivers, pulling mountains up out of the ground? Landcraft, a 3-D terrain generator created by a team of Russian developers, may be just what you've been looking for.

The online interface lets you select surface textures, add undulations and change the angle and intensity of the sun’s light. Try replicating a real-world environment, or get creative and sculpt a Martian landscape.

This new method for visualizing terrain promises to be useful to developers and students alike (no more flour-and-water paste landscapes for me!).
