Aside from flashy graphics, there tend not to be very many "catchy takeaways" in the world of computer science that interest outsiders. Learning to program 3D graphics can sometimes be a complete mind binder for aspiring programmers while they learn to master not only their chosen language but the mathematics behind the 3D principles. While many tools and libraries today have begun to hide that complexity, a project by Peter Rakos featured in Gamasutra demonstrates a 3D graphics engine using Microsoft Excel. What is especially intriguing about his approach is that using Excel's spreadsheet layout allows a programmer to watch the variables change in real-time.
