very epic line pattern. here is some tools. 1. up arrow is changing the size. 2. C is cloning the line by 10. 3. Color option will be at the top. 4. J is line following your mouse.
NOTE: if you have seizures/epilepsy, make sure to not put the colors to 50 or low half or high half. it will flash a lot if you do. (ONLY IF THE SIZE IS TOO BIG)
