Grid-19 is a representation of a speech balloon. According to Wikipedia, speech balloons are divided in 3 categories: speech (smooth border), thoughts (bubbly borders), and screams (zigzag borders). This particular one is a hybrid of all three: it has a zigzag "tail" (scream), smooth borders (speech), but does not display text--it displays an image instead (meaning thoughts rather than speech).
Grid-18 uses shapes that meet at corners to create the illusion that they are somehow all sharing the same line. I used this technique to express my inspiration, which came from simple stitching patterns such as those found on pillows. Nothing too complex here: just a reflection over the y-axis and simple geometric shapes, which can arguably yield to pareidolia.
Grid-16 is Aztec and circuit board-inspired. The grid is open from the left and right sides of the piece where a polygon with four rectangular protrusions faces outwards. The elaborate polygons can be seen as a representation of a system such as a circuit board, or a diagram such as a mandala or an Aztec Cosmogram, both of which are representations of the universe.
