Here, thoughts to help get it done…
Ideas. Instructional designers generally don’t create because they get thunderbolts of inspiration; they create because they get assignments. A friend of mine who offered her talents pro bono to a local charity now has a portfolio piece and a great client recommendation.
Also, consider redeveloping old work projects — without proprietary info and with the cool ideas your budget/timeline/boss wouldn’t allow the first time.
Software. You know about educational discounts and trials. If those won’t work, record a PowerPoint presentation that simulates branching or invest in one application that you can use to create several kinds of projects.
If you focus more on design than development anyway, partner with a student/out-of-work multimedia developer. Violà, portfolio pieces for both of you!
