Gravitas is a physics and Gravity toy. There are currently two toys in this toybox: Chunky Orbits & Rock Tumbler. Chunky Orbits is a friendly simulation of free-floating objects based on Real Life physics. Each object in the scene attracts each of the others in a cosmic tug-of-war. Tap out a few boulders and contemplate the wonders of the Universe. (^_^) - Create and destroy colorful boulders - Add trail effects to visualize the paths they take - Add an absorb effect to grow bigger boulders - Create a sun-like CenterStone and create your own solar system! - Zoom in for a close-up with the BoulderCam - Spacey, happy music-to-ponder-by included Rock Tumbler is a simple bit of eye-candy. It's a sphere full of colorful rocks and gems. The rocks tumble towards the screen with a swipe of your finger. A pleasing display of gravity at play.
