I always lay Luke on the floor in Isaac's room while we clean up his room and get ready for bed at night. I left to do something and when I came back Isaac had the lights all turned off and was showing Luke his helicopter with flashing lights and music. Luke was totally mesmerized by the thing. It was quite funny. It was hard to get a picture with the lights off, but the flash didn't capture the moment quite right either. Here's both pictures.
