The frames I use are all homemade by our family company TH Sack.  The video shows my son working on an order of 100 frames that were needed for a future exhibition. Originally the video was made for family only, with "Scatman" by Scatman John playing in the background. However, due to copyright issues, the song had to be removed. Nevertheless, it is still interesting to watch, and there is no law against playing your own music alongside.
