CLAIM

1. The ornamental design for building block assembly, as shown and described.

Description:

FIG. 1 is an assembled perspective view of the building block assembly shown in a cube configuration formed from eight (8) tetrahedron blocks as shown in FIG. 8 and thirty-two (32) one-eighth octahedron blocks as shown in FIG. 9, which in turn form a series of eight (8) mini-cubes as shown in FIG. 4.

FIG. 2 is another assembled perspective view of the building block assembly of FIG. 1;

FIG. 3 is an exploded view of the building block assembly of FIG. 1 showing the eight (8) mini-cubes as shown in FIGS. 4 and 5;

FIG. 4 is a perspective view of a portion of the building block assembly showing the mini-cube used to form the building block assembly of FIG. 1 in which one (1) tetrahedron block as shown in FIG. 8 and four (4) one-eighth octahedron blocks as shown in FIG. 9 are magnetically connected to each other to form the mini-cube of FIG. 4;

FIG. 5 is another perspective view of the mini-cube of FIG. 4 used to form the building block assembly of FIG. 1;

FIG. 6 is an exploded view of the mini-cube of FIGS. 4 and 5 illustrating the one (1) tetrahedron block as shown in FIG. 8 and four (4) one-eighth octahedron blocks as shown in FIG. 9;

FIG. 7 is another exploded view of the mini-cube of FIGS. 4 and 5 illustrating the one (1) tetrahedron block as shown in FIG. 8 and four (4) one-eighth octahedron blocks as shown in FIG. 9;

FIG. 8 is a perspective view of one (1) tetrahedron block used to form the mini-cube of FIGS. 4 and 5; and,

FIG. 9 is a perspective view of one (1) one-eighth octahedron blocks used to form the mini-cube of FIGS. 4 and 5.
