Papercraft enthusiast site Paper Replika has fun papercraft models of the Apple 1 and Apple II available for download in PDF format. What better way to spend a lazy winter weekend afternoon with the kiddies, than printing out and assembling your own vintage Apple computer? The site has a huge selection of other models (even one of Steve Jobs) if you want to make more.
The site uses AdWords pretty extensively, so I’m linking directly to the Creative Commons License the site wants you to agree to before you can download the models. Another minor detail, the PDF file is password protected with ‘paper-replika.com’. Have fun!
