We had a project in year 3 (maybe 1980-81).
We had to make "Something from the Future That We Will All Be Using".
I made a phone (made out of cardboard) that had a special antenna, with a design such that you could fold the screen onto the keypad so that it would be small enough to fit in your pocket.
My idea was that each portable telephone would have it's own number - like normal telephones, but they would transceive thru special antennas that everyone could have built on their roofs.
My teacher at the time - Ms. Robertson laughed. She said to me - "Who would want to have to answer their phone where ever they went at whatever time of the day or night?"

Well. Suck it Ms. Robertson.

On the other hand it's somewhat telling that the first thing I do when I leave work is turn my phone to silent or often off and rarely look at it again till the following morning.

But you could only see it clearly
with the cardboard tube telescope that I invented.

Yeah that's like this kid we had at school who was a formula 1 driver and invented radar first out of stuff that he found in a skip.
Last I heard of him he was in prison for impersonating a police officer

Not for chopping a drug dealers head off with a samurai sword and shoving the body down a rubbish chute?

We had to write about futuristic gadgets and I invented a wristwatch-shaped telephone which you could wear and talk to your friends on.
Here's its snazzy name - the Wristwatch Communicator, or W. C. for short.

I did spot that unfortunate connotation in time to scribble it out and call it The Communication Watch instead. Didn't Apple come up with it again last year? Plagiarists.
