  What I've seen was a moving pendullum clock (not on a circle, like
propeller). There is a software on my web page written by John Becker
? on EPEmag. The LED's are mounted on a pendullum.In fact the
pendullum it's reversed (up side down). The image is not smeard but
crystal clear with blue LED's. So probably we are talking about
different things, or the movement speed it's different.
