We've got our eyes on Abby, she's going places already. Also, I want a play day in that fort!
From Joe: "Attached are some photos of me and Abby learning about icosahedrons and building her new fort in the backyard, after prototyping it with 3D printed sockets we designed that fit Q-tips as structural members. We then used 2x4's and door hinges to make the full size version."
In geometry, an icosahedron is a polyhedron with 20 faces. The name comes from Ancient Greek εἴκοσι, meaning 'twenty', and ἕδρα, meaning 'seat'. There are infinitely many non-similar shapes of icosahedra, some of them being more symmetrical than others.
