Tufte's seminars:

http://www.edwardtufte.com/tufte/courses

This isn't a workshop, but Lynda.com has a huge number of professional graphic design video tutorials, including a "creative inspiration" series in which design professionals talk about their work. It's a subscription site, but they have free sample videos and you can sometimes find a free 3-day pass via Google.

I think longer than one day would be better.

Also look at art & design schools - they sometimes have shorter seminars. I.E.

The Tufte seminar is really amazing, although it's just him talking (nothing hands-on). You also get copies of his books as part of the deal.

Also looking for hands on, make things.

TypeEd looks awesome. When did it start up?

The TypeEd site does look pretty good. As does its content. While I understand it’s presently fashionable, and the design of the site is in itself a marketing piece, I strongly recommend setting your body copy to black instead of grey. When viewed from even a slightly oblique angle it becomes very difficult to read on certain monitors such as my MacBook Pro. The primary navigation almost entirely disappears and I need to adjust my seat or screen in order to use the site at all {I didn’t even notice the braces around the wordmark until half way through composing this}. While my eyesight a little less than average—irregular astigmatism in both eyes, corrected to normal as best as possible with glasses—even with direct viewing I need to increase the type size by ~200% in order to read the majority of your content without squinting and straining my eyes (and deepening the wrinkles in my forehead ;). I’m confidant a salient typographic hierarchy can be achieved without resorting to grey text.

Chris, I'm also using a MacBook Pro and while their gray type is light I can read it, even when viewed at an oblique angle. And I'm in my 50s and wear bifocals. So perhaps your monitor is a bit lighter than mine, or your astigmatism is a factor.

But I agree that it's too light (I especially notice it on the "We're not referring..." line). Normally I'm okay with gray type (for example I think Apple uses it well at their site), but TypeEd went a little too light.

That aside, I’d still be curious to know anyone’s rationale for reducing contrast on key typographic elements such as body copy and navigation. I can’t wait until “big and easy to read” becomes trendy.

Gray type usually doesn't bother me, but small type does. I usually set my browser to bump up the type size, but I've seen business cards and other printed pieces where the type is so small I can barely read it. I suppose my age is a factor.
