JavaScript Purple Portal Effect

[combatking0]

I think I'm happy with my purple portal effect now - it uses 128 particles which whizz around a circular area after exploding out from the centre.

An additive blending mode is used to achieve the glow and the particles leave behind a trail which fades out to prevent the effect from turning into a white circle.

I've put it onto my Stormbringer page: http://www.barcodebattler.co.uk/stormbringer/

excellent effect ck! and the code is really portable too. reminds me of a high powered microscope looking at purple bacteria. nice one, i will probably have a mess around with your values just too see what crazyness happens

Thanks, Nino I might make the circle a bit smaller since it dominates the page a bit too much, but I'm happy with the overall effect.
