I was a little distracted while I was doing my block. This is the result! Do you see what I did wrong? Anyway, I had to undo it, and start over. This is what happens when you try to do two things at the same time. I was watching TV and at a certain point I was more into the program then into my block. Well that teaches me for trying to do two things.
As you can see, another block is nearly finished.
