Often with Fingertapps projects we find it is the combination of touch and multi-touch gestures with interesting visual effects that really bring an interaction to life. Our latest effort takes the concept further and enables the user to trace their finger across the screen and create lightening as they do. Very cool.
More Technical "Two buffers are created in OGSL. The first holds a touch map which decays over time. The result is that as you move your finger around the screen it leaves a fading trail behind it. The second buffer is a height grid. This is perturbed by the motion triggering ripples."
