Penrose pattern #1, 27/6/11:
The Violet

Title: The Violet
Date: 27 June 2011
Type: Pattern
Number of tiles: 300
Color breakdown: 165 purple, 75 yellow, 60 blue
Shape breakdown: 195 kites, 105 darts
Kosher Penrose tiling rules: no
Supplier: SeriousPuzzles.com

Notes: Penrose patterns mean I want to make a finite shape that may or may not include gaps. This one has little white triangle gaps and a central pentagonal gap.

There will also be Penrose tilings, which means patterns without gaps that when repeated will fill an entire plane.

Rules of Kosher (or Halal, no prejudice): Gaps are not allowed in Kosher. Rhombi, where a dart and kite meet to form a parallelogram, are the other unacceptable pattern in Halal.

You might see faces in these patterns rather than a five fold symmetrical flower. That's called pareodolia, the name for the human tendency to see faces in even completely random patterns. It was a valuable evolutionary tool waaaaaay back in the day, and it's still part of our standard mental skill set.

This gives you an idea of the size and what it looked like in the room.

Changing the focus and light intensity in iPhoto gives you an idea of the geometry in my head when I designed this.

Get used to these. Or not.

Either way, there's going to be a lot more of them.

I'd be glad to know what you think of them, positive or negative.
