- Kurisuteru, on 10/12/2007, -3/+37No, they cannot be realised in physical objects - however, they can be _simulated_ and will look good from one specific angle only.
While that is "cheating", the objects look cool. - radu79, on 10/12/2007, -5/+12Check this out too (no, not my blog)

See the right side links as well. - blahblah, on 10/12/2007, -0/+6Moebius ring is not impossible to realize in real life.
- Trjn, on 10/12/2007, -1/+6Seeing as Escher's works only really worked because they were drawn from one specific angle (at least, the more elaborate ones), it really isn't surprising.
A few other attempts have been made to do Escher simulations, my personal favourites are the ones made of Lego, which I would link to, but I'm having issues uploading them, pretty sure they are easy to find on Google though. - The_Wallbanger, on 10/12/2007, -0/+4Don't forget what would happen if M.C. Escher were growing up in today's public schools.

Remember escher is a printer first. His lithographs and woodcuts are physical objects.
In fact he made several of his prints by carving (er engraving?) large wooden spheres and then rolling them in ink and then on the printing surface.
Some of the more crazy patterns he did are actually blue prints for making such carvings on 4 dimensional 'spheres.'
Escher is cool. - newevilmind, on 10/12/2007, -0/+2these are scaled down models, I thought maybe someone had built "relativity" or the intertwining staircase one the size of a building.
- codplay, on 10/12/2007, -2/+4There are a number of ways of making Escher's impossible objects appear real in a physical form.
This site simply shows them as a single molded piece. As you can see though, the illusion only works from one angle - and can only work from one angle, the angle of the drawing that Escher made.
The other way to make this in 3D form is to model them broken. So, the pieces are not attached, but when viewed at the correct angle, it appears that they are.
It is true that they look interesting, but I personally get no more out of seeing them made with a bent, plastic looking material. In fact, I would rather look at the original artwork. It just has a certain feel to it - a feeling that a bendy object can't get across. - Bluezdood, on 10/12/2007, -0/+1Escher is one of my all time favorites. Good stuff.
- hah456, on 10/12/2007, -0/+1yep, must be a lot more clicks than diggs
- ntnwwnet, on 10/12/2007, -0/+1Hrm, a college webserver being taken down by a story with only 87 (at the time of this comment) diggs?
- bubbagump, on 10/12/2007, -0/+1Reminds me of a great/awful 80's movie...Labyrinth. They built parts of "Relativity" for the big screen...a couple of great mind-bending images...
I digg it, but foam rubber is easy to work with. I would have been MUCH more impressed if they were built out of wood... Ironwood would have really impressed me... - diceone, on 10/12/2007, -0/+1also:

- Wavey, on 10/12/2007, -0/+1The Moebius ring, of course, is not an impossible object, so no great feat there to create it as a real object. In fact, it's super simple: Take a strip of paper. Twist one end of it 180 degrees so the opposite side faces up. Tape the two ends of the strip together. That's it. You've just created a one-sided object. To prove it, take a pen and trace the same trail around it that Escher's ants make. Your pen line will cover "both" sides of the strip.
- Micrll, on 10/12/2007, -0/+1Yes my High School owns one it makes it out of a powder that's glued together. Its VERY solid but they can easily break, they are very brittle.
- electrichead, on 10/12/2007, -0/+1To sidetrack a bit, those models were made on the 3D printers from Z Corp:
http://zcorporation.com/products/printersdetail.asp?ID=3
which means they were modelled on a PC first, and printed. It's not really rubber, it's actually pretty solid. - Criterion, on 10/12/2007, -0/+0The creativity for Escher to make the original images is many times that to figure one (of several) way to make a physical object that looks similar to that idea. The idea of an "impossible object" is that the object is built (or rather, is unable to be built) as it appears at first glance. The fact that there are ways around that now, using 3d computer modeling, is *nowhere near* as outstanding as the original works. In fact, some of them look outright crappy :/.
- radu79, on 10/12/2007, -4/+4Why the hell was the above comment moded down? Not only it linked to a very interesting site, but it had a working version of the waterfall, with video and everything ( http://mightyillusions.blogspot.com/2006/04/eschers-waterfall-contructed-in-3d.html )
Jesus, people, check the URL before using the mod down button. - Xalorous, on 10/12/2007, -1/+1It's not one sided. At any point, it has two sides. The side you're on and the opposite.
It does, however, have only one surface. - iWorks, on 10/12/2007, -2/+2He's not a true emcee.
- everfalling, on 10/12/2007, -3/+1this was linked to in another post concerning escher.
- noeljohnhoward, on 10/12/2007, -4/+1awesome!
- brownspank, on 10/12/2007, -5/+2"Moebius ring is not impossible to realize in real life."
Nor is Relativity, provided you don't consider gravity in the equation. - PantherX, on 10/12/2007, -5/+1It was modded down because it was posted last week.
- PantherX, on 10/12/2007, -5/+1Wow, just a week ago I got flamed and got like -40 diggs for saying this exact scenario was possible.
- ophello, on 10/12/2007, -5/+0*****...for now...
- inactive, on 10/12/2007, -15/+9Holy crap. I was just looking at some Escher pictures 10 minutes ago.
Anyway, this is old news. Optical illusions aren't "actual physical objects". No digg. - pjh3000, on 10/12/2007, -10/+3Yo yo yo, MC Escher in the hizzle!
- Harry, on 10/12/2007, -12/+3This was on Digg before...
- 10scott10, on 10/12/2007, -10/+1they can be molded out of plastic
- thanasi, on 10/12/2007, -15/+2Mr. Wizard was doing this stuff in the 80's.
