Here is the Sonic Sight n' Sound book. You've seen this thing elsewhere, as it was translated into at least a couple of languages and then released in Europe. It was clearly a successful item in it's time. It seems low-tech now, but the re-use-ability of the time must have been very interesting.
The cover says it has "7 Random Light Adventures" and "Comes with Wipe Off Marker". It has thick card pages with glossy surface so you can use it over and over. There are tiny lights inside that, when you press the yellow 'press' button, will do some random flashing pattern to interact with the "game" on that page. This helps control checker-like situations, simple maze type items and other games where you have to help Sonic pass whatever it is. It also makes various noises as you go. There are instructions for each one. Do you want to read all the pages to see what the games do? Now you can! Use this page and click on the pictures to enlarge so you can read the whole thing.
