It was Museum Speelklok. There's an exhibition going currently titled "Robots Love Music".
When the rest had left, I made a punch card playing the beginning of the video game Yoshi's Island. :D https://youtu.be/yvCWXmiJA-E (very poor quality video and sound, a small downside of my Nokia)
Sounds like fun, it's an interesting topic. Visited their website, the trailer video is cool. Also good job on the punch card, Yoshi's Island is my favorite GBA game
