A quick project I made under 20 minutes. An interactive and simple generator of making a OP square spiral art. Modified with sine pulses and rotation effect. All you have to do is type in a number of the pattern type and speed! If you want the thumbnail spiral, the number is 12. WARNING If you are epileptic, be very careful with the speed number. But it really depends on the pattern type. Mostly pattern numbers which almost look like a pinwheel (i.e. 45) Set the speed to 1 before going crazy. UPDATE 31/2/20 - Updated thumbnail. - Added a speed variable. - Updated filter. CREDIT Everything is made by myself.
