My Grandad was an inventor, and one of his best inventions (if he’d marketed it, and got the patent in a reasonable time) was a spherical version of the Rubik’s cube. He invented it and applied for his patent two years before Rubik! The game itself was not the same, but the principle behind moving parts was essentially the same thing.
I don’t go running around telling everyone I meet about this, but when I do mention it, nobody tends to believe me until I tell them to go look it up.. Here’s a copy of his patent: GB1344259 – Amusement Device – Spherical 3x3x3
The other invention that I remember the most as a kid was GB2134687A – Display Apparatus – “The Box”. This was a small wooden box that would plug into audio equipment. It had a diamond shape set of LED’s that would show the phase of stereo sound. Mono would just show up as a vertical line right through the middle. One of the benefits of this device was there were no moving parts, so it was much quicker to respond than a volume unit meter with a needle which was the norm back then.
Granada Studios bought some from him for use on Coronation Street back in the 80’s. ‘The Point’ in Milton Keynes wanted a huge one that would fill a wall as it’s a very mesmerising light show, but backed out when found out how expensive it would be.
I’m really pleased to see that someone has developed a software version of this invention. Not only that, but they took the time to research a little about my Grandad. You can see Chris Allinson’s work here. Chris, if you see this, I’d love for you to get in touch with me!
