    Could somebody please explain what a “geometric snowball” is? When I think snowball I think round like in sphere, and that was its geometric shape. What am I missing? Modern “math”? [Editor's note: The photo was added after initial publication, and after this comment.]

    It’s actually really more ‘old math’, it is an Archimedean solid.

    I’ve been having fun making them in random places around town for weeks.

    WOW!

    Robert, do you have any photos of the molds in action? Do you use silicone spray to get good, clean release?

    “Euclid alone has looked on beauty bare” [link] although I guess that was planes, not solids.

    These have an austere beauty that is magnified by their impermanence. Thank you for this gift.

    Rob, they are so awesome!

    I actually went online and found the math worksheet that I used with a student a few weeks ago…when I saw the snowball, this sheet popped into mind [link]

    Thanks for doing these!

    Surprise encounters with ephemeral works of public art make me feel lucky to be here & now.
