There! Now you see what I mean. At an angle looking stright at the corner will make the lines line up. Would SOMEBODY PLEASE make one, and post it. I know somebody here has a digital camera, since you posted the images of the 'blocks' that you used on the semi-impossible triangle! Here's how to make it: Get a box: ____________ / /| /___________/ | | | | | | / |___________|/ Remove the labled sides: ____________ / XXXXXXXX /| /___________/ | | | | | XXXXXXXX | / |___________|/ You will then have: ____________ /| /| / | / | | |_________| | | / | / |/__________|/ With lines to show sides: ____________ /| | | | | |/| /|| | | | | /|| |||_|_|_|_|_||| ||/ / / / / ||/ |/_/_/_/_/_/|/ Hmm, that made it harder, didn't it. :-) ____________ /| | | | | |/| 1/|| | | | | /|| |||_|_|2|_|_||| ||/ / / / / ||/ |/_/_/_/_/_/|/ If that box were viewd from an angle that made point 1 line up with point 2, it would make the image. Would the person who did the impossible cubes pictures please do that and post it? Who was that?.?.?. Ah, Veronica Karlsson did it! Veronica.......................... Actually, hmm... Looking again, you may need to scrunch the box a little to make it look EXACTLEY like the first image, but it is still possible. Hmm.... ___ | ___ .'| | | .'| | .' |___| | .' |___| .' .' .' | .' .' .' .'__.' .' | .'__ .' .' | | .' | | | .' |___|.' | |___|.' There! That stereogram shows it!

The added 3D info shows the brain how to handle it properly. Many illusions fail to trick when a 3D version is shown. > Add those together and it's 'impossible'.
