For most blocks, we'll either have to skip a row or a column, (or both!) so I shaded out those rows/columns. Just remember to overlap the blue points with another repeat, so there's no discontinuity in the pattern.
Lissajous figures are interesting curves that occur in systems where oscillation happens in more than one direction, for example when a pendulum hanging from a string moves in the plane.
These pictures are from an easy persistence of vision approach to playing with Lissajous figures. Read more about this project here.

first page of the handout from my introduction to the internet on 10/12/93 (coincidentally, my 40th birthday), when I worked at the University Center at Tulsa (now OSU-Tulsa). The first site I accessed on the internet was NASA.
The basic ratio for the kind of flour glue I make is 1 part flour to 2 to 4 parts water, mixed and added to 20 parts boiling water.
Attention: Please do not waste your time and talent by mounting your beautiful needlework with tape, glue or adhesive spray.
From top left: 1. Cut acid-free matboard to fit with some excess fabric. 2. Place matboard on 100% cotton backing fabric and cut a piece slightly larger than matboard. 3. Cut thin acid-free batting to fit matboard. attach using acid-free adhesive spray. 4. Machine stitch backing to long edge of needlework. This photo shows the needlework with backing attached on top of the matboard. 5. Flip and stretch backing fabric to opposite side and pin turned under edge closely. 6. Use same technique on the remaining sides. Keep as taut as possible. Use the lines in the needlework fabric to keep it aligned with the matboard. Whip stitch or ladder stitch backing fabric to needlework fabric. As it isn't glued or taped to the board. you can make slight adjustment to the position even after it is stitched together. Use a fine tip permanent marker on the backing fabric to add your name and date.
I often find cheap packages of matboard pieces in the framing department of Hobby Lobby. They are the matting cutouts.
Upholstered headboard with 1/2" drilled holes.
Foam, batting, and fabrics should already be attached to the wood Tapestry needle (a long upholstery needle is even better)
Embroidery thread, scissors
Covered Button (see the how to for fabric covered buttons)
Needle nose pliers
Backing button that is larger than 1/2" drilled hole
