I’ve enjoyed playing with graphics since I was ten years old. My dad brought home a HP-85 computer from work which had a tape drive, a built-in thermal printer and a monochrone display. Very cool for 1981.

I remember what a thrill it was to get a dot moving around the screen for the first time.
The manual had lots of interesting images in the Graphics chapters. I remember playing around with the maths functions to see what would happen (though I had no idea what cos or sin meant).

Just for fun, I wrote some HP-85 programs using an emulator a while ago. Here are some images.
(The one on the bottom right was a gravity simulation. Two objects in the upper left corner wove in and out of each other’s path for a while).
When I was a teenager we got an Apple 2e, then an Apple 2gs. Full colour palette!

A few years ago I had a block of time between jobs, so I wrote some plugins for a C# program called Paint.NET. The largest one was called Curly Lines. It started off drawing lightning, and grew from there.
