  • After studying the intricate designs of a pound note, Denys Fisher came up with the idea for the legendary pattern-drawing toy, Spirograph. It won the Toy of the Year in 1967 and had sold over 30 million by the time Tomorrow’s World caught up with him in rural Scotland, hard at work on his next creation.

      Denys Fisher, thinker, engineer, & inventor of the Spirograph, died 17
      September, 2002, aged 84.
      Forty years ago, in 1962, Denys Fisher, working in the Yorkshire
      family business, King Fisher Engineering, of Leeds, had the idea for
      the Spirograph, a fantastic educational toy that was to make his
      fortune. It took three years to bring the idea to fruition.
      The Spirograph began its life as an idea for a pattern drawing machine
      for industry. Fisher worked for years on the idea before he hit upon
      the method of ensuring a high degree of mathematical precision.
      Fisher's next problem was how to apply his invention to industrial
      work, but his family were so intrigued by his creation, which could
      produce a multitude of intricate and colourful designs, that he
      decided to market it as a toy.
      The Denys Fisher Toys Group was formed in 1965, and, in its first year
      of operation with only 12 employees, had a turnover of £30,000. In the
      late 1960s the Spirograph became a legend in the toy world, and was
      voted the best educational toy for four years 1966-69.
      In the early days Fisher enlisted the services of Robert Fieldhouse,
      whose job was to make marketing and financial sense of the Spirograph
      bonanza.
      The capital for expansion came early through the sales explosion of
      the educational toy. Pre-tax profits of the group climbed from £70,000
      in 1966 to £337,000 in the following year.
      Much of this came from the licences to produce Spirograph in North
      America. Indeed, the key to the Denys Fisher Group's expansion in
      those days was the inflow of royalties from overseas.
      Fisher headed the company until 1970, when General Mills, the
      multi-million dollar American food combine, took over the business.

    A few years ago I wrote a modest-sized Python script that could generate curves of various types--trochoid (spirograph), Lissajous, Maurer rose, spirolateral, nested polygons--with different parameter settings, colours etc, and let some children play with it on the Linux computers at a local community centre. As kids do, they came up with some ideas I hadn’t thought of. Like what happens if you use a huge pen thickness, for example several hundred units? Yes, you get a fun blobby curve that way.

      There is a direct correlation between people making absurd claims, and them not understanding a definition.
      Yes, I get that it was supposed to be a joke. But the only joke is the lack of knowledge. It would have been funnier if you actually left the word "direct" out. Because then you would have made a true statement.
      Comedy is subjective, and the subject of your joke, is uninformed. Being a moron, only makes you funny for other morons. Don't worry now they'll all come in, and say crap to me like; "You must be the life of the party", "Man, can't take a joke", and so on. You know, the common idiot responses, by the common idiots, who think idiotic statements are funny.

    I always found trying to keep the gears together problematic sometimes.
    This one looks easy enough to 3d print.

    Did you know that there's a direct correlation between the decline of spirograph and the rise in gang activity? Think about it.

    I had one of those! It was very attractive in the advertisements, but after using up the included supply of slick glossy papers, I never touched it again. It lacked the magic of Spirograph, and didn't have the infinite play.

    My fascination lasted as long as the colour biros did - i.e. not very long! A pen running out halfway thru a pattern was somewhat off-putting!
    Never the less, the concept was definitely genius.

    I was amazed to see the milling machine that he used to make grooves in the red plastic sheet, they sell milling machines that look exactly like that today! And it was compute controlled?!
    Did anyone notice the drawing machine seen at the end of this clip (a drawing CNC machine)? It had a small digital readout and displayed prompt messages! I thought machines like that were only available in the 80's, this was 1977! Does anyone know what the name of that machine is?

    We have the same patterns on Canadian money and I'd wondered the same thing, how were they rendered?
    I never had my own spirograph though I had friends who had one (none of us ever had a good enough pen to make good lines though, even the Bic wasn't good enough). That table-top plotter is the bees' knees! At only 1 time in my professional career did I have access to a proper pen plotter (HP), had top quality pens.
    Speaking of shapes and figures, "numberphile" was at Newtyle, Scotland last week with a brand-new aperiodic tile that had been discovered. It's extremely interesting: made from 8 identical "kite" shapes assembled together.

      had a spirograph when I was a boy, I had forgotten about the pins!, the plotter was I think taken up by architects, then later the signmaking industry with flatbed plotters & roll to roll plotters, from signwriting with paint & brushes in the 80's I went on to vinyl cut lettering & now wide format printing.

    • @L4JP

      I worked at HP as a support engineer for plotters from 1985-1988, specializing in the older flatbed models. Although the newer "grit wheel" versions were faster and smaller, those flatbeds were made like tanks and never wore out! The one in this video looks like an HP 7221 or 9872 (same plotter, different interface), and I think he's using an HP 9825 computer. Both the spirograph and the plotter are a trip down memory lane for me!

      Sand leveled smooth then use a water jug hanging from a rope, making a pendulum to drip the water on the sand as it swings.
