Impossible waterfall

A couple of years ago when that big LEGO Architecture Studio set came out Tom Alphin decided to create a 30 day challenge for himself and his readers. Day 12's challenge was to Build and photograph an impossible Escher model out of Lego. He came up with a LEGO rendition of Escher's Waterfall, a scene that others have also tried.

Monument Valley

Iain Heath made this from Monument Valley, a game that uses a lot of Escher-esque scenes and impossible objects, such as this based on the Penrose triangle I've discussed here before.

Happy birthday, Classic-Castle!

In addition to maintaining my little family of LEGO blogs, I'm also actively involved in Classic-Castle.com, the source for all your LEGO Castle needs. Classic-Castle just turned ten years old! In recognition of that, let's feature something appropriately themed. Here is Vitruvian Man, as drawn by Kevin Hinkle. Leonardo da Vinci, 1452-1519, was an artist, inventor, mathematician, philosopher and scientist. He took over 13,000 pages of notes, describing his inventions, his observations of nature and anatomy, and writings on natural philosophy. The Vitruvian Man is his study on the proportions of the human body, in connection to geometry.

Dave Shaddix made this mosaic based on a famous photo of Buzz Aldrin during the Apollo 11 mission.

Impossible objects explained

I occasionally draw something like this on the board and ask my students what it is:

When they reply 'a cube' I correct them, saying that it is a two dimensional drawing that uses tricks of perspective that our mind interprets as a three dimensional cube. Two dimensional drawings of impossible objects take advantage of these tricks of perspective, but the tricks don't match up. So if you cover up one part of the drawing and then cover up the other part of the drawing, different sections appear to be going in different directions. For example, take the famous devil's fork:

If you cover up the right-hand portion, you see three prongs, but if you cover the left portion you see two prongs. However, the lines connect up so at some point the three become two, or the foreground becomes the background. But how to achieve this in three dimensions? The whole idea of an impossible object is that it is impossible. The answer, of course, is that you can only see these from one particular point of view. If you were to look at them from any other angle, you would see that the edges don't match up. For instance ...

Impossible objects

Several of the Escher illustrations depicted over the past few days are impossible objects - two dimensional drawings that seem to be of three dimensional objects, but turn out to be optical illusions, unbuild-able in real life. One of the first impossible objects, and one of the inspirations for Escher's Waterfall and other works, is known as the Penrose triangle. This was actually first depicted by Oscar Reutersvärd in 1934, before Roger Penrose independently presented his version.

The Penrose Triangle was the basis for the Lugnet logo. Lugnet was one of the first major LEGO websites.

John Langrish made this mosaic of the Lugnet Logo.

The Penrose Triangle has been recreated in LEGO many times. Some of these depend on Photoshop trickery, but others are true three-dimensional creaions, such as this by Billy Baldwin.

Brixe63's Modulex version is more remniscent of Reutersvärd's original design.

Various other LEGO impossible objects have been built, such as Don Solo's archway.

Brixe63 has had great fun with the idea in her set of optical illusions.



Brixe63 also has this amazing Terrace, that is based on an impossible scene that was apparently first used by Sandro del Prete (who was influenced by Escher).

Continuing with our look at M.C. Escher in LEGO form, another very popular work is Ascending and Descending:

Probably the earliest version was by Andrew Lipson and Daniel Shiu.
