Q.E.D. "Quod Erat Demonstrandum", used at the end of proofs

Has anyone encountered an interesting hand-lettered or type-set "Q.E.D." before? It's used to mark the end of a mathematical proof. The contemporary digital version is, unfortunately, the "tombstone," a simple black square (yawn).

Thanks!

Help sought with suite of icons using proprietary symbols

Forums: 

Hi all,

I'm developing a suite of icons for use by an organisation. The majority are generic symbols from public domain or developed by me, while others are TM logos or symbols such as word, powerpoint, PDF logo, Facebook etc. It's these kinds of proprietary symbols that have me scratching my head.

Any advice from someone who has been through a similar situation? I would normally seek permission from the company, but I'm unsure about even the language or terms I should use or whether I would run into a brick wall etc. I'm tempted to develop a suite of generic symbols which try and represent these icons without reproducing them but that seems a little counter-intuative or something.

Any help would be well appreciated. Thanks for reading.

Symbols for outdated currencies

Forums: 

In the process of designing a typeface, I'm wondering if it's worth the effort to design glyphs for currencies that are not in use anymore, like pesetas and francs. I realize the symbols might still be in use for historical reasons, but in a display face, I think it's rather unlikely.

How do you guys do? What do you think?

old style figures in mathish places

Forums: 

Does anybody know about how old style figures are used in technical areas that use a lot of symbolic notation like math, most sciences, linguistics, logic, chess books, etc., if at all? I've never seen them in a work of any such discipline, though that's not saying much. I don't seem to recall them in any of the textbooks I used for these subjects, but perhaps I wasn't typographically "aware" at the time.

Thanks in advance.
