"Do you need a break from the daily mobile soap? Surround yourself with soothing space. Simply press your pocket-size BuBL device. Release a bubble of silence. You'll feel pleasantly isolated inside, even in a crowded place. Evaporate all phone signals up to three meters around.
Enjoy the silence."
Christel Vester's wrote about BuBL.Space in Privacy under Attack!: "Dutch artists Taco Stolk and Arthur Elsenaar are seriously irritated
by the use of mobile phones in public areas. They are really not
interested in overhearing your argument with your boyfriend and so on.
In order to protect themselves from this unwanted interference into
their private domain, they invented the BuBL Space. This device
disconnects all mobile phone frequencies within a three-meter radius by
jamming the frequencies. With Bubl Space you can create your own bubble
of silence, re-establishing a 'private sphere'."
BuBL.Space was presented at DEAF03.
