# Environmental Barometer — The Frog!

A tessellation created inside a box of four different mirrors. I guess I like to challenge myself, if you take into account my distaste of symmetry methods that use multiple mirrors.

# 2018:

A list of M.C. Escher show around the globe, for this year and years past.

# Frisbee Dog #Tessellation

This tessellation was done using the Pg symmetry system. Two parallel glide reflections with a few lines snaking from one to the other. In the sketch below, the thicker lines delineate the two characters, the guy and the dog. Not that many lines. The thinner lines add details to the shape. If you want to know an easy way to create this type of nested shape, have a look under the Techniques menu, and choose the symmetry group you would like to use.  Continue reading

# Deforming your tessellations into infinite spirals

A new App called “iO Crafter” on the iPad has just come out, from Jürgen Richter-Gebert. Using it to deform into spirals is where my interest lies. As well, it has other functions to deform your images: build a platonic solid; build a kaleidocycle;  view a kaleidoscope; hyperbolic kaleidoscope; and conformal maps. Continue reading

# Tessellation Artists around the Globe

### Artists

Updated 2023-01-20:

Since M.C. Escher started popularizing “nested shape” tessellations, many artist have dabbled in the field. Some show a passing interest, yet still create with a very deep understanding of the rules of symmetry. Others can’t get enough and create constantly in this art form.

# Sketch to finished drawing in KaleidoPaint

### How to skip quickly from a messy sketch to a finished drawing in KaleidoPaint

Sometimes, I find it difficult to spend hours tweaking a single outline for a tessellation. I’d rather sketch freely to come up with some ideas. This was the only way to do it, before the edit line/fill function came along in KaleidoPaint. My drawings were messy and close to impossible to change without adding more of a mess on top. Sometimes it was easier just to start over on a blank page. The trick I had found Continue reading

# Refining a tessellation — a frog animation

My first ever tessellation, redrawn from scratch, to show the series of steps required to achieve a successfully nested shape.

The original image was a pencil sketch from years ago. Before Windows 3.1 and way before the iPad. And I could not afford an Amiga computer, even less the first Mac. So cardboard, pencils, scissors and lots of graph paper it was. Continue reading

# Puppy Training tessellation

This symmetry group was the first one with which I completed a successful tessellation, the Frogs. Way back in 1988, in the dark ages. Symmetry group P4g. Head to head, elbow to elbow, feet to feet is how I decipher these nested shapes. A very simple technique,  Continue reading

# KaleidoPaint is now on Android!

The Android version of KaleidoPaint is finally finished and publicly available. I would like to share this spectacular and free app with the group Broug Atelier for Islamic Geometric Design.

# Panther Tessellation — Symétruc panthère

A challenge to help my Nephew understand the basic rules of tessellations for a math class. Wish I had been fortunate enough to get an opportunity like this when I was a teen. La leçon est en français à part de ça! Continue reading

# How to back up your KaleidoPaint drawings to a desktop computer

You may wish to save your KaleidoPaint drawings other than by emailing images of them or saving them to your Photos folder on your tablet. In this case, you need to save the actual dot TXT file, a file that gives written instructions to your tablet, on how to recreate your drawing. Continue reading
