you could try browsing for it at a site that lets you narrow your search. i'd try looking for "square fonts" at a site that offers that option.
i bet i've seen fonts very similar as i've browsed every single font (24k+) that showed up in an alphabetical browse at fontspace, but i was just saving fonts to my hard drive until i get a computer of my own and can't browse what i saved.
another option might be trying to browse bold fonts.
trying to find matches though is VERY hit and miss! i didn't see either of the two fonts asked about in previous posts going through fontspace and a bunch of my old favorites weren't there either. that's 24,000 wastes of time to find those fonts.
