It’s just not right using normal bookends for your science fiction and gaming books. Thankfully there are crafty people committed to staying away from all that is normal and boring. Instead of opting out and just purchasing plain bookends, one guy made himself a Portal themed set. All it took was a CnC table, some metal and a little spare time. It’d be great if they opened up an Etsy account and started selling these off to those of us that don’t have spare metal just lying around.
