Default BrainTerrains

A cognitive neuroscientist friend asked for a trio of stylus pens that visually evoke brain terrain/convolutions and ideas.

I assured him that I'm clueless about the origin of ideas, but willing.

These were made with a succession of handmade acrylic mica paints progressing from thin-to-thicker Golden brand acrylic polymers applied with fine brushes. Two of them have .6mm undrilled beads. Cast tube-in at 50psi with Douglas and Sturgess PR. Turned and finished as usual:

He likes them, and I remain clueless.

More fun ahead - I think.

Happy Sunday to all.

- Bob

Those are cool. I stared at them for a while and got the idea that a beer would taste good about now. I probably would have had that idea without stimulating brain terrain/convolutions.

Driving home from my In-Laws yesterday I heard a radio program that touched on this topic:

Very incitetful. Most I did not understand, but enough to realize that it was meaningful, and I should learn more.

Most unusual and colorful. I had an idea once. It died of loneliness.

You won't make me believe that my brain terrain or convolutions are orange, blue nor green, nah. Wdyt? But I provide support to your cluelessness about the origin of ideas, be sure.

A bundle of very pleasant pens indeed Bob. I love your way of searching deeply in one direction.
Create more, kit less.

There are days my brain seems to feel exactly how those look. Again, another realm of pen making. Thanks Bob.

As a neuroscientist, and occasional pen turner, let me say you nailed it right on the 'head' ;-)
