Digital Marble – Desert Chicory

I was going to do a blog post called ‘Circle Quotations’‘ but funny or interesting quotes about a mathematical concept are few and far between. Then I found this one-

Why is a polar bear never lost in the Arctic Circle?
Because it uses Polar Coordinates.

I think you have to be a math person to appreciate the wit, and that isn’t normally me, except I know that the ‘Digital Marbles’ I make in my photo program use a polar coordinate filter to turn square photos into circles.

I don’t know how the polar coordinate  filter works, but I like the result. The circles remind me of the marbles I played with as a child.

Are you old enough to remember when marbles and jacks were popular games? How about skipping and hop scotch; tag, hide and seek, leap frog, and yo-yos? Hula hoops! In the winter, fox and hounds, red rover (skating version), crack the whip, snowball fights and tobogganing!

I made the following two ‘marbles’ from photos of Desert Chicory.

How many degrees does a circle have?
Depends on how long it’s been in school.

These is the original photo. Desert Chicory is a wild flower growing in Arizona.


Here are some of the other ‘marbles’ I’ve made:
