It may take a few tries to be able to form the tower correctly and consistently. It's all a matter of time and practice. Make sure also to keep the pinch with your freehand middle and index fingers as you swing into the tower; it's pretty much crucial to make the tower look as recognizable as possible.
Presque vu is a French term meaning "almost seen." It's the phenomenon you have when you feel like something is on the "tip of your tongue" but you can't quite think of it. It's also closely related to deja vu ("already seen"), which probably more people have heard of. Interesting stuff.
