Decided to make a sierpinski's tetrahedron as a first REAL project! I built a shitty angleiron workbench (with an old door ziptied onto it as the tabletop) before but I'm actually trying this time so it's different
170 welds completed so far 
!! So, only 346 left to go!!... 
This was a really good idea until I remembered how complex fractals are, like GIRL, DUH, fuck was I thinking hahaha
Its REALLY scuffed though, I'm talkin like using my stick welder to melt a half inch off the end off of the pieces I had precut to make it shorter so it will fit in the actual dimensions needed, I've been holding the smallest (~2") pieces with a wrench and holding it in place freehand. It's been a lot of fun so far, and I'm definitely improving as I go, I weld my welding stick to my stock way less often now, and achieve arc much more reliably too, which is cool to see my own progress within the project!
I hurt my shoulder a bit ago so I haven't been able to do much lately, but welding is pretty low impact in that I mostly just sit on a folding chair in my driveway next to my shitty workbench lol
Have some more views!
When it's done it'll look like this image I found on google
Mengers sponge is really cool as well though. I like the rhombic dodecahedron because it has some nice mathematical properties like tesselation, symmetries, it retains a lot of the properties of a cube (since it's "made" from one) but isn't nearly as boring. I wonder if mengers sponge could be made with rhomic dodecahedra as wel...
