On the Canary island Lanzarote an artist called Manrique built a wonderful
restaurant high up a mountain with a splendid view (Mirador el Rio). When
you sit at certain tables it is as if there are extra people at your table,
but in fact they are over 10 meters away. Indeed it's the ceiling or the walls 
there, which are all curved.
