These little people, always facing the wall, invaded Barcelona two years ago and then disappeared.
They've made a second invasion in the last few months.
The artist is a mystery, as is the significance of the little people.
Some speculate they may have walked into the wall, some say they may be timid and introspective.
Either way, it's a fun Invader-style invasion.
