I've got a square of the Penrose T.P. framed and hanging in my bathroom. I've also got a couple of extra squares I've been saving, thinking I might someday give them away as some kind of award. Dirk, the floor is beautiful so, I'd be happy to send you a P.T.P. square if you want to frame one and hang it in your bathroom. Also, you might consider having a commercial laser-cutting or water-jet firm create a custom drain plate, so you can continue the pattern (as holes in a metal circle) for the drain. It is trivial to do if you can create a vector file of the pattern you want them to cut (but it's not inexpensive). George http://georgehart.com/ On 6/10/2015 8:48 PM, Fred Lunnon wrote:

Not for the first or last time, I failed received so much as a letter of thanks from the commercial enterprise concerned. [Though I was subsequently obliged to --- er --- come clean to Penrose about my part in the affair.]
Moral: if you are approached by an individual with an enquiry of a suspiciously industrial nature, get things --- um --- down on paper beforehand!

Was all the Penrose tiling toilet paper manufactured by Kimberly Clark in the late 90s destroyed, or does some of it still survive?
If there are still rolls out there, and the price isn't prohibitive, you could install some (presumably for display purposes only) elsewhere in the bathroom.
If you don't known the story of Sir Roger's lawsuit against Kimberly Clark, I urge you to look it up. It features one especially memorable quote, from David Bradley: "When it comes to the population of Great Britain being invited by a multinational to wipe their bottoms on what appears to be a work of a knight of the realm without his permission, then a last stand must be made."

Finally, a year after we moved into our new (old) house, I managed to finish the penrose mosaic for the shower in our ground floor bathroom.
I put two quick pictures, before the glass wall was installed, at

Thought some of you might enjoy, Dirk
