It's no secret that Matakishi's Tea House has been inspirational for this sci-fi project, and one of the things I've been promising is an alien artifact-cum-structure like the Face of Boo (as seen near the bottom of this page). A child sized mask would take up the bulk of a 10mm scale table, so that idea wouldn't work. Instead, I combed six different stores before finding this little gem in the discount store for the princely sum of two dollars.
I didn't even need a knife or saw for this one, just snapped off the head and limb. Buried it in a mix of sand and standard white glue, and jammed a bunch of stones into the side of the hill. That's one alien statue, buried in the sands of time.
