High-tech wallpaper keeps neighbors from stealing Wi-Fi
The French think of everything. Scientists in Grenoble
have developed wallpaper that keeps your Wi-Fi signal inside your house in the ultimate preemptive strike against neighborly Wi-Fi theft (other than simply setting a password, that is). The silver crystals that coat the paper are arranged to "block certain wireless frequencies," including that of a Wi-Fi router. If you'd rather forgo that effective, free password method we talked about earlier to cover your walls with this product, we totally understand -- we rather like the metallic snowflake effect ourselves. You'll just have to wait until it's available in 2013.
I wonder if this will work in my tinfoil style hat
