How Crop Circles Are Made

Crop Circle Generation
How to use

Click the copy to clipboard button at the top right of the code below (looks like two squares overlaid), then go to JWildfire, and click the From Clipboard button. The flame will now be ready to play with. Remember to always link to any flame you tweak if you post your images online.

Another bswirl attempt this time with heavy use of hypertiling and some blur for the glow, and a little post symmetry thrown in because it looked more… well… symmetrical ! 🙂
