Calligraphy resources online?

[untonuggan]

Before I start a duckduckgo search that may lead me down the rabbit hole, I was wondering...

• if anyone here does calligraphy?
• if anyone has a recommendation for a teach-yourself-calligraphy online resource (preferably not YouTube because they and my Gnash player don't always play nice and I'm trying to stick to Free Software)?

Whilst cleaning out my pens I found a few calligraphy pens, and I thought it might be worth learning a bit so I could make some stationary or something. Or keep myself out of trouble for a bit, at least.
