When I was a kid, I would make Star Trek phasers out of 5-6 blocks of LEGO max. And I wasn’t creative enough to make a communicator out of the blocks so I would just flip open my wallet as a communicator (I still do sometimes). When my brother bought an actual Star Trek Phaser toy, my minimalist phasers became obsolete.
That wouldn’t have been the case if I could stack the LEGO bricks like Tommy Williamson, who has beautifully built LEGO versions of the Phaser Type-II, Communicator, and Tricorder from the original Star Trek series. The Tricorder even opens up and has working lights. Check out the vid for proof.
