A dodecahedral ball made with bamboo

Again, I saw this interesting dodecahedral ball in Alberto's living room. He told me that he bought this at Vietnam a few years ago.

A nice glass cuboctahedron

Alberto has this beautiful gass box with cuboctahedral shape in his living room.

M.C Escher's "going up the stairs"

I visited the National Museum of Modern Art (Reina Sofía Museum) at Madrid yesterday. My old friend Alberto showed me this interesting stair. Very similar to Escher's work, isn't it?

Of course, there are many paintings by Picassa, Dali, Miro, ... in this museum.
