There are so many TV shows about crime, murder and serial killers, so it seems fitting enough that someone had to make interior wall murals for, well, people who like blood. Specifically, lots and lots of blood stains and spatters — low-maintenance enough to put on and remove easily without a whole lot of scrubbing and mopping. Done wishing? OK, PIXERsize has a whole bunch of blood murals you can mix and match to create your own deranged kill room. Just don’t blame us if your friends think you’re psycho.
