This was actually my very first Blender project ever (created in May 2016). It is based on simple meshes and some video and photo material from my smartphone.
While it started from something quite different to the image shown here, the idea was to make a music video for my own electronic music track with the same name, and the result was a music video on YouTube - but consisting of only a single image, as the quality of the animations was not sufficient in my opinion. Too bad, especially after using almost a week of computer processing time just for rendering animations.
After creating this I had quite a long pause in using Blender at all, broken only by a realization later in November that I (also from a professional standpoint) really needed to put considerable effort on learning to use the tool, and to create a 3D artist portfolio of my own.
The music "video" can be watched on YouTube at https://www.youtube.com/watch?v=Ad_HBR8WPqA, but it seems that it's too large to embed here.
