My first introduction to graphics was definitely the type-in-program listed in the back of the (orange) manual I received with my 48k ZX Spectrum. It drew a UK-flag.
Here's the source, which gives me a moment of nostalgia:

I wrote a simple BASIC interpreter recently, in golang, and hacked in support for outputing PNG images of code. I should see if I can get that sample to run (mostly) unchanged!
- ggambetta 7y agoNice! Some time ago I worked on a ZX BASIC interpreter in Javascript, so it could run on browsers. My idea was that kids these days™ don't have an environment as easily available and immediately gratifying as we did back then, so I wanted to make one! Have you considered doing something similar with yours?
- stevekemp 7y agoI did embed it in a web-server, so that the user can enter BASIC into a <textarea> and have the output rendered by their browser as an image. I called it "visual basic" ;) https://github.com/skx/gobasic/#80-print-visual-basic https://github.com/skx/gobasic/#80-print-visual-basic Just a small example really of embedding, I suspect to make it really useful for new-programmers it'd need a lot of overhaul. When my child gets old enough I'll probably just give them a BBC-emulator, or similar to get started with.
