Things you can’t do without?
This is one of my favorite pieces of software, it was only a short while since I discovered it, but it’s one of those interface additions that I got used to immediately:

FoxyTunes for Firefox is just one of those indespensable things you can’t do without once you’ve started using them. When looking for skins for a mediaplayer I’ve always wanted them to be compact and functional, but now I don’t think there’s any better way to save desktop space than having the controls right there on the browser.
Something you maybe can do without is Belgian artist Wim Delvoye’s Cloaca machines (I suggest to unblock the pop-up on the first page).

What Cloaca does is to artificially digest food and produce the closest possible analogue to human feces. I didn’t learn about this work of art until recently, and I’m not going to present any sort of thorough analysis of it here (analysises by people much better at such things than I am can be found in the essays section of the Cloaca site). I just wanted to mention it because I find the whole concept intriguing. I mean, what else can you think about a big, expensive machine whose only purpose is to produce shit? Maybe the only useful aspect of it is to be a an example of near-complete uselessness.
