Mesmerizing and Intriguing. I LOVE IT!!
To make cool designs, move a finger or two around the screen. If you get a nice one, tap the upper left for the menu, and the lower left to save that design.
With the menu screen open, on the bottom is a series of frames. Click on a frame and the design will morph into the design you tapped.
You can record a video of your Fraksl session, too.
