"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.

Halloween 3D is a playful dress-up scene for iPhone and iPad. A scarecrow stands on a hill under a drifting ring of clouds and a gnarled old tree; you decide what it wears, what surrounds it, and how the night looks. DRESS THE SCARECROW • Six pages of decorations around the edge of the screen: masks and heads, hats, shirts, pants and dozens of props. • Tap an item to put it on the scarecrow, tap again to take it off. Picking a new hat or mask swaps the old one out for you. • Pumpkins, lanterns and other lights glow on their own; pick a moon to hang in the sky. • Three hills to stand on: grass, stone, or snow with real snowflakes instead of leaves. • Clear All puts everything back to the bare scarecrow in one tap. SET THE SCENE • Lights on or off: turn the room lights down and the sky, clouds and tree fade so the glowing props stand out. • Shake the device for a flurry of autumn leaves (or snow on the snow hill) that spiral down around the scene. • Reset brings the camera, lights and decorations back to the start. LOOK AROUND • View mode hides the menu so you can drag to orbit the scarecrow and pinch to zoom; double tap to recenter. • Save a picture of your scene straight to your photo library. • Halloween music and sound effects, with a one-tap mute. Your scarecrow is saved when you leave and is waiting when you come back. No account needed. Halloween 3D is free and supported by a small banner ad that appears only while the decorations menu is showing; a one-time Remove Ads purchase takes it away for good. Happy Holidays!

Halloween 3D's advantage is ratings volume (896 vs 57). On price, update cadence, ads and in-app purchases there is nothing between them.
