The Response

(name Redacted):

Just the fact that I have to take the time to respond to your absurd claim about my copying M.C. Escher’s work “reptiles” infuriates me to no end. I suggest you thoroughly read what I’m about to say then go back to your dark corner where you belong and put your dunce cap on.

1. Do you understand the art of tessellation? Simply put, it is the repitition of IDENTICAL geometric forms (either animate or geometric) which cover a single plane indefinitely.

2. I have studied Escher, and am a big fan of his. However, his drawing in question has a couple problems. For one, he never took the time to technically resolve this particular tessellation. He was a master illusionist, but in this case he only made it appear the reptiles were indentical, which in fact they were not. Simply trace his 3 central figures, stack up the tracings, and what do you get? Three distinctly different shapes. Not only that, his hexagonal geometry was only approximate, not precise. (See attachment “escher reptiles.”) Copyright laws are quite precise, you can’t have your cake and eat it too. There’s a lot of dead architects whose work Escher copied for his various drawings. Plus it’s a well known fact in the art world that artists use similar themes from other artists, Escher included. It’s all but impossible to truly have original ideas, esp these days.

3. My design is not only distinctly different in many features, BUT I TOOK THE TIME TO RESOLVE THE TESSELLATION. Anyone who’s done any serious tessellations knows this to be a fact. Further, I have discovered along the way several other artists who also created their own version. My first copyright on my GeckoStone design and tessellation was issued in 1994. I revised the artwork again with a new copyright and revised tessellation in 1998. (See attachment “gecko C1994.”)

4. My work is well known in the field of tiling and tessellation and has been viewed as similar, yet distinctly different than Eschers, both in US Federal Court (below) in Seattle, and having been published in many established magazines and books (all major publishing houses) – who wouldn’t dare do such if I was indeed infringing on Escher’s work.

5. Now a few years ago one idiot (coincidentally a Dutchman by the name of Deboer from Canada) had the audacity to copy my original design and market a concrete paver resembling mine, setting up mfg in Canada, then distributing knock offs of my work all the way from Washington to California. I sued the
whole food chain for infringement – and guess what? I won. I put him out of business. (see attached August vs. Deboer, et al)

6. On top of that, during litigation the defendant Deboer forced me into a summary judgment by the court. It cost me over $20,000 to prove (on this one point of law alone) that not only did he copy me, but my design was also distinctly different than Escher’s. You know what the judge said? “I see more similarities in yours and August’s design than I see anything with Escher. Escher’s drawing is irrelevant as far as I’m concerned.” The summary judgment was ruled in my favor. (see attached summary judgment)

The case files are public record. Why not spend your time there and not waste mine. You should be paying me for your legal & art education.

So my suggestion to you is inform your fellow greedy foundation members to go take a hike. I expect a formal letter of apology written to the address below. If you are dumb enough to take legal action, keep a couple things in mind: 1) I’ve already established a legal precedent; and 2) Your company will be locking horns with not only myself but some VERY BIG publishing companies, and it will cost you more money and time than you can even imagine to press for a lawsuit. And if you do, I will also counter sue you for harassment, and demand both compensatory and punitive damages.

Tread lightly,

More practical for a geeky tiler are the penrose tiles

Penrose himself tried to sue a toilet paper manufacturer for using a design like this.

Bad idea all around,they’ll break almost everywhere, and the edges would be impossible

Also, here is the License Agreement:

At an economic volume the breaking & spalling issues would be simple to address. Then again, looks like he’s the litigious type given the copyright attempt..

Side note: did anyone else have this as a puzzle as a child? red, yellow and blue geckos? I wonder if that was copyrighted..

More practical for a geeky tiler are the penrose tiles as seen in my universities chemistry building.

…turns out to be a variant of Truchet tiling

Well, I would not be surprised if this work is already public domain. In which case they don’t need to licence the work to use it.

(I don’t know when this precise drawing was done by Escher, he started working on tessellations around 1936, and copyright lasts 50 years, or 70 years… so…?)

But, of course, copyrighting the work is ridiculous!

I’ve always admired it but didn’t realize it was prolly used in a lot of places.

These have been around for years, and are not identical to Escher’s drawing. It may have been Escher’s idea, but copyright doesn’t cover ideas, as Cory is so fond of reminding us. A patent might have been more appropriate.

So how do they stop the people who buy the tissue paper from seeing the design?

Don’t you read the EULA on your bogroll?

Escher’s estate should sue their testes off.

But you definitely don’t want to look to that guy for architectural tips. Ever since I installed that stairwell in my foyer I can never remember which dimension I left my keys in.

*Interlock: (definition) “to connect so that motion of any part is constrained by another.”

Thanks, geckostone!

Did you see those officially licensed soft tiles linked to in the comments? Interesting.
