I needed a pull cart for my current project. I'm not much of a hard surface modeler, so I could have bought one on the internet, but somehow I felt obligated to make the car myself.
At first I regretted starting it, but after a while it started to grab me and I happily worked on it for much longer than I could have ever imagined.
I made a quick video montage of my screenshots and renders using Corel FastFlick. And after some extra polishing in Corel VideoStudio, I posted it on YouTube.
It is not a tutorial, rather a randomly compiled overview of the creation of the 2 carts.
