Now the Etch-a-Sketch, that beloved toy which started life in the 1960s and amused children for the next three decades, is coming back - thanks to the help of the iPad.
Inventor Ari Krupnik has created an almost exact replica sleeve of the Etch-a-Sketch, including those two big twiddly buttons with which you can sketch on your designs on the grey screen.
Plug an iPad into the belly and - hey, presto! - everyone's favourite toy has come back to life.
For the re-birth of Etch-a-Sketch, Ari worked on the software side, emulating all those beloved features to make this identical to the original - so shaking your iPad will clear your image just as before.
Although there is a nod to modern times - you can share your pictures via Facebook or Flickr - or even send a timelapse video to YouTube.
