Painting inside of Trompo Grande
« on: June 01, 2019, 08:26:09 PM »

Bought several TG's awhile ago that we're mostly clear plastic.  Today, on a whim, I decided to paint the inside of one.  I wanted the cap to stay clear, so I chucked the tip in my drill, dribbled some craft paint inside, and gave it a spin.  I should have known better.  I expected the paint to fling around laterally in the direction of the spin.  But, because the sides are angled, the paint wants to climb the walls and fly out the open top.  Good thing I was in my yard work clothes.  Anyway, the end results are pretty cool.

Really cool colors and patterns! Did you experiment with drill speeds?

So, there was a whole plethora of unspoken disclaimers for this post.  My box of acrylic craft paints range in the (very roughly) 30 - 4 year old range.  If you pick up a color you like, it may,  or more likely may not, still be reasonably fluid. The end result of color choice was not the original concept.  Drill speed... due to the viscous state of the paint, started out conservative, ended up full blown liberal/devil may care. After the high speed spin with paint creating it's own flying vortex, I decided I wanted more lateral dispersion, and turned the top on it's side to allow the paint to flow.  I rotated it several times during the dripping/drying process.  Then I had an errand to run, so the photos are the top riding shotgun on the dash.

Ha ha, that's too funny.  Totally could see myself doing the same thing.  Looks great!

<snark>Ah, but what does it look like spinning? Just blurred brown?</snark>

Sorry, couldn't resist.

Does it look brown?  You decide

It's hard to capture what it looks like to a human eye.  The camera freezes the motion.  My phone camera only goes down to 100 ISO.  I would describe the color as sort of coral overall, blending more purple toward both the tip and the crown.

Looks a little like a Singapore Sling, right before you pass out. How did you get your yard to spin like that?

Ha!  I was trying to get all the angles of light, so I was also spinning.

Way cool - much better than I imagined. I like the moving spiral effect.

I have the same experience with the color-mixing tops I make. Video never captures what I see in person or in long-exposure stills. With the right patterns, the videos can be interesting for the frame-rate and rolling-shutter effects they add, but the desired blending of colors is pretty much lost.

I've come to the conclusion that every patterned top has 4 "personas" that may differ dramatically: One at rest, and at speed, one in person, one in video, and one under a variable-speed strobe. The moving personas can be difficult to impossible to predict from the resting pattern but are fun to discover and design for -- usually with much trial and error.

The top doesn't look blurred brown, but when I run real fast my socks do.   ;)
