I had one of these as a kid and could just about manage a square. :(

No, they´re actually not fake. We saw a document here in Finland about a guy who can do wonders with those. He has done those his whole life...

I had one and couldn't even manage a bad circle. :rolleyes: A friend sat there for 5 minutes and draw an amazing picture of a little Hansel & Gretel like cottage! It can be done...
