click hereHow does it work?
because I'm not prepared to download a PowerPoint presentation from a site that I know nothing about.I imagine others might feel the same way.
The second group of cards you see contains non of the cards from the first group.
I got it as an attachment, then googled it to show you. Never thought of the risk, sorry.sidecar sid, thanks, brilliant.
You asked how it works - the card you choose is not displayed, but neither are any of the original set. One obviously concentrates on one and thereby you assume that it is only that one which is not reproduced to you!A interesting piece of illusional psychology :-)
Quite liked that..
