Gosh.  That's a nice effect for such a (relatively) simple source.  I think I actually understand some of it :lol:

 

Many thanks for both the effect and the source TechnoRobbo!

EER - Thanks -the code is actually some unused routines from developing PasteWarp. It takes a warped mind to make a warped plugin. 

 

CC4FH,DD and Seerose - Thank you, your kind. Nice examples too.

 

DD -It does look liike Darth Vader. I should have published it on May the 4th  not May the 5th. May the 4th be with you.

 

(OK, OK, I sense a disturbance in the force, like millions of voices groaning over a bad joke).

Oooh.  Now you can move the bean anywhere in the world you want to!  Like.

 

The Doctor: There was a goblin, or a trickster, or a warrior... A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.
Amy: But how did it end up in there?
The Doctor: You know fairy tales. A good wizard tricked it.
River Song: I hate good wizards in fairy tales; they always turn out to be him.

Honestly , I think that bean is weird. A city with architecture by Mies van der Rohe ,Frank LLoyd Wright and the Columbian Exposition legacy has a bean?

 

 

Many thanks to david. pixey , doughty, lloyd, treveroutla and especially to Mottoman for the turkey homage.

 

Red has pointed out that Alpha channel should be taken into consideration and I agree. I will publish have published an Alpha-friendly revision - Thanks Red (reps from me)

The bean is weird.  But being close to it is a fascinating experience.

 

Does calling it "cloud gate" make it better? ;-)
