Today on In Case You Missed It: A miniature circular saw printed on a 3D printer is about to be produced by a designer so that it actually cuts wood. Teeny tiny little thumbs best be careful. The Spider concept car by Swincar is out, climbing 50 degree inclines without a hitch and making everyone want one. Finally, the Lexus Hoverboard is shown actually being ridden in a new video, rather than just inside the promotional glamour-shot pieces we've seen so far. It looks just as cool as we'd hoped.
