Pinch is a hypnotic and inspiring aesthetics exploration toy that allows the player to easily generate many kinds of abstract shapes. A virtual sheet is made from free-floating physics masses. Click in different places to apply forces making the masses move towards that area of the screen, hence "pinching" the sheet. The resulting forms look organic, architectural, and sometimes erie. Pinch is highly customizable and exports to OBJ format to be imported by 3D software. Change the texture by replacing texture.png. On the mac, this is inside the app package contents under Contents/Resources/media. In the same folder, change the color pngs to customize the interface.
