Playing with Lite Brite

I found the boys playing Lite Brite in my older son's room this afternoon after school.  They spent a good 45 minutes working on this picture together.  They were so content and shared the picture board so well.  My older son was very patient - making sure his brother was doing it correctly and telling him what colors to put on what letters.  They kept turning the light off and working on it in the dark to see it all lit up.  It was priceless.
