Some of us like to take the simplest things and make them complicated. Like this door chain for instance. This thing will make it beyond complicated to get the door open, keeping others out and keeping you in…forever!
The Defendius was created by mad genius Art Lebedev. I understand the concept and it’s a good one, but maybe a medium sized maze would have been best. Something between the original and this crazy labyrinth. Still, I guess if there are people you really don’t want to see, you can always blame the Defendius. And when they find your corpse after two weeks, half eaten by your cats, they will know the Defendius was installed.
