A wearable device for Gordan Savicic's "Constraint City: The Pain of Everyday Life", includes: "A chest strap (corset) with high torque servo motors and a WIFI-enabled game-console are worn as fetish object. The higher the wireless signal strength of close encrypted networks, the tighter the corset becomes." Whether it is meant to be painful or pleasurable seems unclear.
I suggest exploring the link below to glean the project's conceptual background. I find its discourse reminiscent of Stelarc's. I do share the artist's interest in sensing the electromagentic waves permeating our environment; even to the extent of mapping it to haptic feedback. However, regarding the restriction of the public through normally undetectable information layers, I do not share his tenet that secure WiFi networks are as actively constrictive as this project asserts. Perhaps wireless security cameras and traffic lights are even more controling than secure WiFi, since private citizens should have the right to encrypt their networks from the public without suspicion of conspiracy.
Imagine this: you're an informant with really really sensitive data. You have an algorithm that the NSA wants for themselves, in the right person's hands it would cause a revolution, but in the wrong person's hands it could lead to an era of tyranny.
You need to get your data to your contact. You have his key, but you can't be seen with him. At any moment you could be stopped, searched, or even killed.
This is where JanusBox comes in. It looks like a suitcase, except for a subtle vent on one side, but the payload isn't dead trees, it's a linux server with a very sophisticated system for keeping your secret data secret.

For starters, the system uses two VIA PadLock Mini-ITX C5Ps with hardware entropy and AES 128/256 - some wicked fast encryption. Secondly it has 700 gigs on board that use an AES256 cloop xfs. For all this encryption, you have a pass phrase with optional USB root plug keys using cloop XFS encrypted partions. AES 128 or 256 can be used with keying via SHA256 or 512 respectively. Finally the case features a padlock to discourage any kind of physical access.

But no encryption is secure if you also have your keys with you. This is where the really cool feature comes in- the Dead Man's Trigger.
Right under the handle of the suitcase lies a very important button. When pressed it forces your encryption keys out from it's volatile memory, as well as resetting both motherboards simultaneously, thus rendering the AES256 hardware accelerated partitions inaccessible. At this point, you can hand over the suitcase, and be confident that all you'll be releasing is pure entropy.
The creators, coderman and goldy of JanusWireless, are so confident in their design that they're taking it to this year's DEFCON with the SSID "hackthisidareyou". If they can can withstand a conference of eager hackers, it will likely stand any major attack.
