3D list game

Keeping people entertained, the idea of a game in a gallery. Give people a list, artefacts/photos in a room, need to tick items off your list. Only some of the lists can be completed, others could be in response to a test for example or a riddle, others remain incomplete. Would this play on people’s Zeigarnik response? 

I gave my family a list (copied from a found list) and asked them to see what items we had in the kitchen. Was this fun? Was this annoying that it couldn’t be completed? What surprises were there?
