Post-Knitting Project?

Blipper Soozaday mentioned fixing up her shady sitting area that might include a "shiny horse trough." I envisioned something more like these, rather than the galvanized troughs used for raised beds and first used as stock tanks, that she probably meant. If you ask me (but who did!), I think these horsey planters would be more in keeping with her yard; besides wouldn't it be fun to spend time growing your own 3' horsey chia pet, which is basically what that one on the top is?
