Another project watchers might find interesting is the top post on r/Excel, where someone made a video player in Excel because his machine was completely locked down.
My favourite (ab)use of Excel, which is already on your list, is using it for HDR photography[0].
While I'd never use it for day-to-day anything, things like this are a really interesting way to show how things like HDR photography actually work. Excel can be very approachable for stuff like this.
Wow! This is really neat.

For another completely insane but kind of fun way to abuse an office application, see "On The Turing Completeness of PowerPoint" [1].
(Gwern has a whole list of accidentally/surprisingly turing-complete things at [2])

Why...
Because the person who did it found it fun to do? I believe the site is called 'Hacker News' not 'Sensible and Useful Engineering News'
If you have to ask a question like that, it's doubtful that you'll comprehend the answer: Fun.
