Turntable Optical Illusions Book
By bohus
This may be the item that fits the most Retro Thing categories ever! Clearly this is a book, it deals with optics, and it uses a turntable to make the magic work. The first section of the book details how many popular spinning optical illusions work, the second part having full-page optical illusions that can tear out. The book has a hole through its center, so once you tear out the full page illusions you can pop them on your turntable.
The book explains that while you can see many of these illusions by spinning the patterns on a pencil tip, they work better with constant rotation like that provided by a turntable. The part that might be the most surprising is the publishing date of the book: 1992. That's quite a bit after turntables were on their way out of many households. The book's intro makes mention of this, joking that this book will help you get some use out of that "obsolete turntable" you didn't throw out yet.
I won't agree that record players are useless - to the contrary, this book is just one more use for your platter spinner! To think that it used to just be the music I chose to put on the turntable that made me dizzy!
