This question relates to the OEIS sequence A279212.

Fill an array by antidiagonals upwards; in the top left cell enter $a(0)=1$; thereafter, in the $n$-th cell, enter the sum of the entries of those earlier cells that can be seen from that cell...

Note: "that can be seen from" means "that are on the same row, column, diagonal, or antidiagonal as." Basically, you're adding up previous terms in cells to which a queen could move on a chessboard.

Here's an animated example that shows how the sequence is built:

My friend Peter Kagey and I have been thinking about the parity of the terms of sequence and have created a bitmap to represent our results. In this bitmap, white cells represent odd values, and black cells represent even values. Click the image for a higher-resolution version with the first $2^{12}$ columns and $2^{13}$ rows.

We think that the resulting "parity map" of A279212 has interesting structure, and we wonder whether this pattern has a name and/or has been studied before.
