Not as far as I know but the website has a little sort of effect which you probably already figured out however.
"Fan them out, the backs are yellow. Close the fan and repeat, now they are blue! Again you do it now they have stars! One more time, there are red, white and black stripes! Now show the faces. They appear normal. Again, now every card is blank! One last time and there is a large dragon! Each card has a small piece of the dragon, forming a large mosaic when spread."
So I reckon its just your imagination to come up with something else.
