I don't have an interactive R2-D2 in my life. Welcome to my first world problems, but there is at least a first world solution: the Star Wars R2-D2 Interactive Astromech Droid. This is a roughly foot-tall robotic replica of R2-D2 that not only moves, it responds to (a limited range of) vocal commands. It will activate a light, alert you to movement, and play Princess Leia's recorded message. Oh, and it makes all those awesome R2-D2 noises that continue to delight us almost 40 years after Star Wars was released. This has been around for a while, but if you haven't seen it check it out (there are a lot of videos on YouTube). It's priced at $199, but Amazon is offering it for $175.85 to Prime members right now.
