Hi All!
I'm a thesis student at OCAD (Ontario College of Art and Design) in Toronto, Canada, and I'm trying to start up a typeface foundry at our school called Xheight.
The foundry will promote, nurture and distribute student typeface design through the web. There's also a printed annual component.
Please help my research out by doing the survey at www.xheight.org ! Suggestions are much appreciated as well :D Thanks!
Dear typophiles,
I am doing background research for the TypeCon Education Forum this summer where we will discuss what might comprise a post-graduate degree program in typography here in the U.S.
Please look over the list below and respond by identifying any areas which you have been educated in, have had training in, or have investigated on your own in order to further your typographic work.
This survey is meant for anyone who considers that typography is central to their main line of work. You do not have to be a type designer. Also, feel free to add any areas you think have been overlooked. My objective is to learn what kind of backgrounds those who are currently working in the field have.
