This is a kickstart for a pizza oven that goes on your grill. I'm putting in my support for one.
Hope they get to their $25,000 in a few days and can fill their orders for this pizza oven on the grill.
Similar project (already met its backing goal, only 13hrs left right now) for a portable wood-fired pizza oven. Kinda wish these both had a version with a little more clearance for loafs. :)
This stand-alone, portable wood-fired oven looks more promising.
