In 1993 the Future Crew released the seminal demo “Second Reality”. One of the more simple effects they showed in this demo was the “Dot Tunnel”. It is a simple, yet mesmerizing oldskool demo effect. We can build on our knowledge of fixed point maths to implement this effect and maybe even improve on the original!
