the color-changing abilities of squid and octopuses

December 10, 2005

It has to do with chromatophores, which are pigment cells in their skin.

In other words, if you accessorize with a squid shawl, it will likely adapt to the colors in your outfit very fast since the chromatophores are linked to their nervous system. Squid also change color when they’re upset, so watch out for their famous ink defense, which comes in fashionably dark shades.

Squid can do this color changing business without high tech help, but we humans are not so versatile. Now there’s something called a chameleon shawl (squid shawl doesn’t have the same cachet, does it) with pixels containing color LEDs. There is also a sensor within the fabric that sees the color of the garment closest to the shawl. A coordinated color is picked by a microcomputer.

You have to admit that squid shawl brings up an interesting vision. On the one hand (tentacle), it has the suction cups to stay where you put it, on the other hand (tentacle), it has the ability to move wherever it wants to.

People are beginning to look a little more rushed. The lines at Macy’s were very long, but elsewhere they weren’t so bad.

It’s in the 60’s, and there are just as many shoppers in jackets as there are those in t-shirts, shorts, and sandals.

No painted ones, just the greenish-white, pink, and deep red, with some that look like a paintbrush was flicked at them. I got these.

At Home Depot, there weren’t very many flowering plants other than poinsettias and cyclamen.

I picked up 10 lbs at the farmers’ market this morning. This stall also sells Fuji apples, and I was just ahead of two ladies who were getting ready to sink their fingernails into some pristine ones.

Charles Bonnet Syndrome

People with this condition see vivid images of things that are not there. These visual hallucinations can involve strikingly detailed lights, elf-like creatures, faces with scary eyes, or people who disappear.

It generally afflicts people who lose their sight late in life. Many probably do not report their visions for fear of being thought mentally ill.
