Each entry must feature some kind of inlay. This can be wood, glass, metal, etc. Epoxy pours are not allowed per /u/kevin0611's request. An epoxy pour does not count as an inlay for the sake of this contest. (Example would be cutting a pattern on CNC or by hand then filling with a colored epoxy to give the illusion that it's inlay.) Bowties, marquetry, and banding are good examples of allowed inlay in this contest.
A receptacle or circuit that is overloaded is a hazard, in particular one fused beyond its limits. Power tools, especially heavy-duty saws, require lots of amperage, and you may need to add a circuit or two to serve the increased demand in your workshop space. Some tools re­quire 220-volt service, so you may want to install a special plug and line to power that high-powered table saw.
As the comic George Carlin might say, a shop is mostly just “a place to put your stuff.” The physical aspect of a shop is indeed simply a space of some kind — a garage, a barn, a teepee — that keeps the rain, rust, and robbers away and houses a collection of implements needed to saw, plane, slice, sand, and pound raw wood into useful objects. But just like the difference between a house and a home, what transforms a building full of tools into a comfortable workshop goes beyond the mere physical aspect.
