Fixed Pants™ Posted October 11, 2006 Report Share Posted October 11, 2006 That ones crap, is all it is, is the inverted image of jesus, if you open it in paint and press ctrl and i it doesn't work, but being the genius person i am i took a print screen then did it, its just a picture of jesus (or what is portrayed to be jesus and inverted.

Token Posted October 11, 2006 Report Share Posted October 11, 2006 okay, nicely spotted, but that still doesn't really answer the question.The Triangle still has the same area and just because the gradient(right word?) seems a little bit offset half way down does that really make it have a 'hole'?

JT! Posted October 11, 2006 Report Share Posted October 11, 2006 (edited) Cant quite remember, but the gridlines arn't stright too. By combining both that and the convex hypotenuse they get a spear square. Edited October 11, 2006 by JT! Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted October 11, 2006 Report Share Posted October 11, 2006 Just thought I could figure that one out on PS.I cut all of the shapes out of the 'full' one, and moved them to the same order as the one with the hole..yet there's still a hole.

Token Posted October 11, 2006 Report Share Posted October 11, 2006 so theres still a hole even when done accurately? I dont like getting bummed.... Quote Link to comment Share on other sites More sharing options...
JT! Posted October 11, 2006 Report Share Posted October 11, 2006 The reason that people sometimes find this puzzling is because they start off making an assumption. Often they don't even realize they have made this assumption. The assumption is that we are comparing two triangles, and that they each have the same area. Certainly a quick inspection - helped by the grid - is that the 'triangles' are 13 squares across, and five squares high, and they kind of look the same. In fact the top triangle is not a triangle at all, it is a tetrahedron. If you look closely along the line of the hypotenuse (the diagonal), you will see that it is not quite straight, it is slightly concave. Why? Well, the dark green triangle is 5 squares across, and 2 squares high. The red triangle is 3 squares high, and should be 7.5 squares across for the hypotenuse to have the same angle to the horizontal. In fact the red triangle is 8 squares across, and the angle of the hypotenuse is slightly shallower that that of the green triangle. Which is why the hypotenuse is not a straight line, when you look closely. The bottom 'triangle' is not a triangle either, it is also a tetrahedron, but now the hypotenuse is slightly convex, since the position of the red and green triangles is now reversed. Here is an image of the two triangles superimposed, which shows the difference in the two hypotenuse... The area of the two 'triangles' is actually the same, since it is made up of the same pieces. But because the lower 'triangle' has a 'hypotenuse' that is actually convex, this extra area is the equivalent of one square, which is why the lower shape has a missing square.

Tomm Posted October 12, 2006 Report Share Posted October 12, 2006 It's obvious what it means, and there's a picture on the PDF anyway... Not rocket science! I made one, it's very cool, but I find you have to be a long way away for it to work. If you close one eye it works much better, but most people don't do that.

Danny Posted October 12, 2006 Report Share Posted October 12, 2006 It says on the pdf to use one eye that way you dont get a 3d perspective on it. Works great about 30cm away from it with one eye closed. Quote Link to comment Share on other sites More sharing options...

Works great about 30cm away from it with one eye closed.If works with two eyes too if you're far enough away. Or quite close if I take my glasses off Quote Link to comment Share on other sites More sharing options...

If you close one eye it works much better, but most people don't do that.i found you had to use one eye but now it works with both eyes open which is quite wierd because it moves all the time now.

monkeyseemonkeydo Posted November 3, 2006 Report Share Posted November 3, 2006 Ok so it's not really an optical illusion but look at this...Apparently children see a picture of dolphins since they have no concept of anything sexual. Whereas dirty minded sods have trouble finding the dolphins at all!!Dave Quote Link to comment Share on other sites More sharing options...
Davey Posted November 3, 2006 Report Share Posted November 3, 2006 Hahaha, it literally just took me about half an hour to figure out where the dolphins were.... but I am a very dirty boy so it's not surprising!Davey Quote Link to comment Share on other sites More sharing options...
