Walk on the beach

1) a huge experiment in physics
as the waves hit the concrete wall, they bounce back and interfere with other incoming waves. this creates a huge pattern of wavefronts (that you can barely see in this picture...), with the constructive interference causing a spike in the ridge in the junctions where two wavefronts meet.



2) written in stone
The stone wall is scarred with all sort of love statements, names, faces, drawings, cartoons, and what not. This is my favorite...
