@Pink_Hat: When I didn't have a Lego version of something, like a Droideka, I kept looking at the Lego Star Wars video game model and used pieces to create it.

It's pretty cool there's instructions for sets online, maybe even for the old castle sets.

@vex714: Aw man, I still want an original droideka minifig so bad. And the big Technic one, that one's really cool.

Actually, the website has pretty much all instructions since the late 90s freely downloadable. It's come in handy for me many a time
