Calling all current and aspiring Interaction Designers! I just found a spiffy resource for you:
Open educational materials - made by the world's design elite
That tagline is certainly calling my name!
They boast quite a collection of open access textbooks to further your design knowledge. There are also videos, research, courses, conferences, a design library, curated toolbox and an educational initiative.
Most of the content is free outright and a few things are free if you join the organization.
It looks promising! I'm heading that way now...
