I\'m on a mission to document programming the ZX Spectrum Next. Between making the instructional videos I need to learn how the machine works. I thought it might be fun to document this process too. In this video I work out how to use fixed point maths to make things move around the screen in pleasing ways, ready for the next video I\'m releasing next week. It takes a lot of effort to produce a video explaining how to program a certain aspect of the Spectrum Next, most of that effort is me learning something new and trying to find any documentation on it. I get a bit lost along the way so if I make videos and you watch them, it\'ll motivate me to carry on!
