Bounding diamond

The Bounding diamond of a pattern is the smallest diamond that fits the entire object. The diamond is diagonal lines meeting up with a side length of 1 or 2 depending on the size.

The block, tub, pond and generation 5 of the T-tetromino represent the edges of the bounding diamond of width 2, 3, 4 and 5 respectively. The "octagon" phase of the octagon II represent the edges of the bounding diamond of width 8.

edges of the bounding diamond of widths 1-10. The width 1, 6, 7 and 10 edges are sparks, width 2, 3 and 4 are still lifes, and width 5 and 8 are (or evolve into) oscillators. (click above to open LifeViewer) RLE: here Plaintext: here
