i've seen two such things.
a terminal emulator, that can do WAY more than is typical. graphics and video, not only "barely achieved in a rudimentary way" but actually far outstripping any other means of cruising through your images and video...
... now if only i could find them again. grrr.
[edit]
ah, wasnt too painful to search for (lies).
found mention of http://www.enlightenment.org/p.php?p=about/terminology (http://www.enlightenment.org/p.php?p=about/terminology) or http://acko.net/blog/on-termkit/ (http://acko.net/blog/on-termkit/) or http://xiki.org/ (http://xiki.org/) via arch forum.
terminology i think is the one i was thinking of.

(not the best video of it in action, just the first i found this time.)
~update~
tried installing from the github following not the readme (which was bs), but instead following (some of) this: http://comments.gmane.org/gmane.comp.window-managers.enlightenment.user/19208 (http://comments.gmane.org/gmane.comp.window-managers.enlightenment.user/19208)
i gave up when stumped by no libtoolize or glibtoolize availability.
probably will have more success with trying that other repo... maybe.
