40 Years of Lego Space
It's been 40 years that lego has been making space sets, and I don't think that this contest is without coincidence. So here would be a great, fun, simple build that could suit all ages. This little monument has two Classic Space minifigures with a big Classic Space symbol, and '40 Years' written under it all out of Lego bricks. The letter designing was a little tricky but it would be easy to recreate with instrusctions and is stable (everything is connected to the main build. I think this would be a great thing to remember the years of Lego space gone by, and the many more to come!
