Excitedly introducing Marble Track 3

(started 04:50 Wednesday 20 May 2020 JST)

I am sketching out my plan for presenting Marble Track 3 to people online today at 9:30 my time.

Here is a video of me presenting Marble Track 2

Predictably, responses to the video were in two main camps.

Some people were like “How did you make it??”

Well, start with a wooden base, then put two sticks on it to act as guideways for marbles. Here is one of the end points for large marbles

And there are more images. You can see them here https://b.robnugen.com/art/marble_track_2/

Hmmm these pictures don’t really show every detail. Wow wouldn’t it be cool to have a video where each piece of the track just appeared in place? It would just seem to 3D print itself.

Nah; that would not look realisitic..

Here is my first attempt at a video

Here are some behind the scenes bits of the first time

I lost the images, camera, camera holder, and we moved.

I learned a lot from making the first video. I want to have a rotating stage, a better camera mount, and a real camera.

Fortunately, I decided to splurge and get a real tripod.

And now, if you are still here, you can see the video snippets which show the construction so far.
