Visual Illusions: Lilac Chaser

Stare at the center cross for a few (say 30) seconds to experience the phenomena of the illusion.

vi.lilac.chaser(np = 16, col = "magenta", bg = "gray", p.cex = 7, c.cex = 5)

`np`	number of points
`col`	color of points
`bg`	background color of the plot
`p.cex`	magnification of points
`c.cex`	magnification of the center cross

Just try it out.

NULL

In fact, points in the original version of ‘Lilac Chaser’ are blurred, which is not implemented in this function.
