I was going through this book and I absolutely fell in love with typography as the main highlight of installations.
I'm making a portfolio and I was wondering would it be okay to submit an installation piece involving typography (with the design process) as part of my portfolio? I'd be using cardboard and some paint and printing out the dimension stencils.
Or should graphic design portfolios be mainly include print and web designs?
Depends who you'll be submitting the portfolio to.
If it's a higher education institution then there's no problem about including that.
If it's a business who needs a web site done then it would best to leave it off.
