The security feature has become increasingly difficult for hackers to beat, but former NSA staffer Patrick Wardle found a way to piggyback on outgoing feeds and record them.

A painting by artist Jorge Pardo is taking work away from bull-slinging gallery explainers.

That honor belongs to the iPad set into the lower-right corner of the piece that can let anyone who walks by connect to Pardo via Skype.
