Papercraft-creator extraordinaire Steo has vowed to release a new papercraft model every Monday. Yesterday's creation is a series of models based on Valve's Portal. Steo says that this is just the first of four Portal waves he hopes to create.

The good news for us: These models are easy to put together. You can download your own blueprints and pieces here. Also, make sure you visit Steo's Nice Paper Toys page on June 4 for the second batch of Portal paper models!
