This looks quite nice and very interesting, with the cogs and the little figure in the corner. However, I just don't think this is the right portal to post it in. The Art Portal does accept GIFs and, even though this is a longer loop, I do think it would fit there better and would be fine, considering that the only thing that really changes through the 20 seconds is small, non-specific movements. Not a thing where it'd be too long to post as a GIF, because different points of it can be viewed with the same experience, more or less, if you know what I mean.
