"Gloop" sits somewhere in that improbable space between an interactive lava lamp, foam resting on water and alien clouds lit by the setting sun(s). Whatever it is, as you stir this bizarre mix thousands of virtual molecules collide with each other, sticking and slipping. This generates heat causing the gloop to glow and become less viscous. If you treat the gloop more gently it cools and solidifies allowing you to give it form. Gloop FREE now features warping of photos, images and real time video on iPhone 3GS+, iPod 3rd Gen+ and iPad+. Photos and real time video require a device with a camera. ------------ Also by RunSwimFly - "Germs" and "Germs FREE" - the liquid physics engine of "Gloop" employed in a game of microbial conquest.
