How do you know what weight and shapes will work to create something like this? How long would this kind of piece have taken from concept to finish?

good ride

Use marble or carbine nanotubes, because these creations of your should last forever!

[MrKaddan]

@davcroy Do you use ball bearings for these amazing creations or just some really loose fitting metal pins?

[davcroy]

@MrKaddan. This was one of my first pieces with all ball bearings. I tried a variety of sleeves but stainless ball bearings work best.

[MrKaddan]

@davcroy How big are your ball bearings? I got inspired by you building some very simple moving creations, and I just searched my parts bin for some bearings.. I found some 3 mm ones. Seem to work just fine, spins for minutes

Looks like catastrophe theory at work!

Wouldn't it be cool to walk into a hallway filled with these things?
