I would say there is no easy way or code we can just hand you.

The best would be, and thats an easy one, to just use a transparent image of an lensflare. You can easily create one using Photoshop. http://www.gamedev.net/reference/articles/lensflare/lens-flare-tut-shot1.jpg
if you have an moving light source or camera, maybe you can split the lensflare into the different rings and move them according to the camera. in this case maybe a different blend mode will get better effects then just transparency.

ok my server had some problems but its back online. so here it is:

http://www.pixelnerve.com/downloads/processing/ss_lensflares.zip

you will need vitamin that is available in the package.

the technique is pretty simple and is based on that gamedev.net article. its lensflares in screen space.

if you are interested in a pure processing version it should be easy for you to port.

V: for me, the most interesting thing about your sketch is that it is grabbing the mouse and returning it to the center location!  How are you doing that?  -- Ben
