it is really fun assemble new filters with the Composer this is...Galactic Twist
the video last only 5 seconds (i have no more hosting space on vimeo so i could not make longer ) but show well a possible effect.
it is based on Nathan De Gargoyle "Twist" and Rectangle2Ellipsoid (humm..thinking now i did not a confront with the effect of the original Twist
but i believe is even more twisted..
no video but a gif...because the effect require the Combine animation mode that is easily available for gif but that i have no idea how to get for video file
sorry if would take time to load
