I've long had dreams of making a post-apocalyptic terrarium (yea, that's how I roll), especially after making one at Clintonville's EcoFlora for my wife for Christmas. But damn if this isn't infinitely cooler. The down side? Yea, it's $185 on Etsy, whereas the terrarium I made, though it didn't have a wrecked RV, mini Walter White in whitey tighties or blue sea glass acting as meth, cost about $15 (or thereabouts).
This does bring to mind some other awesome pop culture terrarium ideas, like a Game of Thrones one with Calisi and dragons, or Star Wars with Sand People and R2D2/C3PO. Any other obvious choices I'm missing?
