I am trying to the learn The Penrose Knot - page 75 Karl Fulves Self Working Rope Magic - and am not(pardon the pun)having much luck.

Does any one know of any other sources, either in print or on video? Thanks.

I thought I saw in other sources, but only found someone's demo of this, and some vaguely similar effects, but methods differ.

I've not done this effect, but my guess would be that the manner in which you create the loops is critical

I don't have the book handy, what is the effect, it may be called something other than Penrose. Or, someone else could have acquired it and called it something else.
John, where's the demo of it?

The effect is that of creating a series of "loops"/"knots" in a length of rope. The magi explains that only one is a real knot, the others are not.
The spectator is then asked to pick any of the loops, and hold on to that particular loop. The magi then pulls the ends of the rope, and all the loops disappear except the one that the spectator chose to hold on to, and (by the picture) it forms a legitimate overhand knot around the spectators fingers that he used to hold onto the loop.

After looking at the "demo" (which I downloaded years ago, and don't know the source), I realized that it is only related, not the same. In the video clip, the magician creates a series of loops (from the string of a yo-yo), but each loop is around one of his fingers. He then pulls on one end and all the loops disappear (similar to the way sewing thread can be pulled away (unraveled) from the fabric if a piece of thread/fabric is cut way.)

I've been pretty diligent about cross referencing tricks, yet each of my cross references were only "related", so I have no other name for the trick, BUT, looking at the text, Fulve's writes that it was invented by Roger Penrose (I'm sure just coincidence)
