Web design tip: don't have animations within a short distance of text, as human eyes evolved to follow the flashiest/fastest-moving thing around, which makes such text literally illegible to many of us. This particular site takes the cake in that regard by animating the whole page background.
The moving background detracts and distracts from the content making it hard to focus.
True, but the site is called Evil Genius Labs for a reason. And it's not too hard to switch off, there's a clear prompt in the bottom right corner. (Didn't try mobile.)
