Enlightenment's Terminology[1] supports a few fancy things including image previews, animated cursors (nyancat is a builtin theme...) and local file links. More impressively, it actually works really well, it's native, and it's fast (even hardware-accelerated). With all of that fanciness, it renders text even faster than suckless' st with a GPU.
