The flitter effect of this CAPTCHA was created accidentally. I wanted to create a CAPTCHA where the letters consist of small squares. I chose the color of the squares to be random. This led to a blinking flitter effect which gave the name to this engine.
At the start the letters assemble from the squares and then blow apart. This is the basic function of this CAPTCHA. The assembly effects can be selected, the erode effect is an explosion with gravity.
The weapon of this CAPTCHA: The method is to be the bug army. The letters consist of small and uniform parts that hold zero information about the solution. The bugs fly over the enemy lines, joins together to form the line, do the battle, erode back and withdraw.
