I am one of those people who are often oblivious of their surroundings, which gives me the advantage to discover things even after years at the same place.

One of these things is Jerald Jacquard’s steel sculpture February, in front of the McCalla School in Bloomington.

It first caught my attention through the sound it makes: Put one ear next to one of the three “legs” of the sculpture, and gently hit another part. Some ambient musician should explore this.


But the sculpture has more to offer. It is made of 28 blocks (one for each day of February). Each block is either a cube, or a halved cube. For halving a cube Jacquard uses two possibilities, both prisms over isosceles triangles, and both exactly half the volume of the cube. The usage of the (in my re-rendering, red) prisms is strictly limited to the lower part of the sculpture, making it to appear more open at the bottom than at the top.


The other (green) prisms are used to create roof-like slopes. Almost all blocks are placed in a cubical grid, but there is one exception.


The front-bottom cube in the image above is moved to be able to support the two prisms above. Maybe, in leap years, one should add another cube?
