I have no idea where I got this, its a program that allows browsing the icons in the /icon folders. It is NOT in the regular menu of programs anywhere, but I have put it in my favorites section. Looking at properties in "Favorites" does not yield a clue about it. It just runs.
Searching for a file in / named "iconbrowser" yielded nothing.
Searching in synaptic for it also yielded nothing.
Trying to run "IconBrowser" with various spaces and capitalization in terminal does not find anything so it must not be in my paths.
It's a very handy thing to have and I'd like to know where it came from so I won't lose it.
