Hi, my name is Sam. I built swings out of legos. I had to program the swings to go up and down, and side to side. I used a program called Yellow Brick Logo. I typed the procedures into the computer and the infrared tower transfered the procedures into a little lego computer called the yellow rcx brick. The yellow brick made the swings work. The swings were fun to build and to play with. Below is a picture of the swings and the procedures.
