This is one of my first experiments (very old now), combining 3D CSS animation with vector graphics (my logo).
I really enjoy working with, and incorporating CSS animation in my work. I particularly love the whole notion of creating animation effects with a core web language rather than via an animation frame-work, which will always have a downside in terms of page speed loading.
I think the final result here, if compressed, is only a few kilobytes, whilst also being fully accessible and scalable.
