Nicely detailed resin, metal, and acrylic replica of the amazing device that allowed Buckaroo's jetcar to pass into and through solid matter. The Overthruster works by colliding electrons and positrons, then collecting the resultant intermediate vector bosons into a beam which when projected onto matter, breaks down the virtual photon barriers to subatomic space. If you're moving fast enough to achieve rotational sync (~700 mph), you can translate right into 8 dimensional space.
