65 flames to play with, using various variations combined to make some cool designs, it uses parplot so the things to tweak are the parplot preset id (1-48) and the weight of the parplot. As seen here.
Once you change the preset ID, then drag to increase or decrease this number. Also play with Colour_mode and umin umax, vmin vmax. This is all just to begin with, tweak anything you like of course. Have fun with them 🙂
