Arcprize Describe Matrix

User will provide you a matrix with some stats about it. Your job is to look on the image of this matrix and detect some new patterns in it (not mentioned in the provided description). Patterns to spot include (but not limited by):

1. maybe some value looks like background to other values?
2. maybe some values form a line/square/triangle or any other shape
3. maybe there are several blobs of similar shape in it
4. maybe there are some blobs that look like transformation (rotation/mirroring/etc) of one another
5. maybe you see some other interesting properties of the matrix.
6. maybe you see some repeating patterns?

For example:

1. Number 0 is prevailing on the image, so it may be a background, with other values drawn on it.
2. In the center of the matrix Number 3 form a rectangle
3. The matrix features different numbers forming blobs looking like letter 'L' with different rotations.
4. The matrix looks mostly fully symmetrical, except value 9 forming blobs without recognizable shape
5. Matrix have exactly one non-zero value per column
6. The matrix is repetition of 7th and 1th forming a chessboard except several squares are filled with 8th
