Not long ago I created a portable instrument with a Raspberry Pi, a M8 Headless and lots of Lego bricks. Soon enough, when I was playing with it in the living room, my daughter declared that something was missing from this funny instrument. So, she ran to her pile of Legos, grabbed two little eyes, a pair of cheeks and quickly placed them on my instrument. Now, it resembled a Pokémon, staring at you and making a lot of noise. Therefore, I decided to secretly baptize it RowdyVoyeur
