Weekend Cat Blogging and Photo Hunt: Flash

7 Comments

It’s been a little while since we have done a combined Weekend Cat Blogging and Photo Hunt. This week’s theme is Flash.

I don’t often use a flash when taking Hipstamatic photos of Luna, but when I do I can get some interesting results.

In addition to the “laser eyes”, we see Luna posing with our heart-shaped kalimba.


Weekend Cat Blogging #368 is hosted by Jules and Vincent at Judi’s Mind Over Matter.

The Saturday Photo Hunt is up with this week’s topic Flash.

The Carnival of the Cats will be up this Sunday at Meowsings of an Opinionated Pussycat.

Weekend Cat Blogging and Photo Hunt: Heart

9 Comments

Our combined Weekend Cat Blogging and Saturday Photo Hunt features the theme Heart. We have a few images that blend the theme with our interests in music, mathematics and of course, cats.

Here Luna poses with a heart-shaped kalimba (thumb piano).

Luna peers at the iPad, which displays a plot of a cardioid. We used a mathematical function that produces the heart-shaped figure when plotted with polar coordinates. The formula for the cardioid is: r = 1 – sin(θ), where r is the radius from the center of the plot and θ is the angle sweeping around the center. The best way to visualize polar coordinates is using one of those old circular radar screens where the plotter sweeps in a circular motion.

The photo also features one of Luna’s favorite toys, a heart-shaped plush toy with the word “kitty” inscribed on it. We have had it for years now (indeed, it was featured in a WCB/Photo Hunt back in 2008).
