Columns went alright. I'm noticing improvement in getting the whole picture consistent with itself when I swap eyes.
Special Tetris is alright. I am still doing red left/cyan right for now until I have something close to parity with the colors reversed.
The light tube went well. I'm noticing that it takes me around five minutes initially to get the left image of the red glowing circle to come in clearly. I will give it a lot of attention and try to get it to come in clearly, but it just takes a long time. Hopefully the amount of time to do that goes down and then it will just begin to happen automatically. There was no need to fix the hypteropia this time around.
