Dutch to English Art/Literary Art, Arts & Crafts, Painting Urban musem

Help please. I am translating an article about an urban museum, which is supposed to be primarily based on the local people's contributions (photographs, stories,...). It supposed to be constantly changing.

Die tonen we in het museum, waardoor het voortdurend in verandering blijft - ...to be shown in the museum, which means that it remains a work in progress.

However, the word "wissel" is used several times (Wisselende presentaties tonen een diversiteit aan invalshoeken.)

Kleine en grote wisselpresentaties vertellen steeds andere dingen over de stad. and WISSELPLEK AMATEURKUNSTEN (and several other wisselpleks)

I am tentatively saying relay presentation and AMATEUR ART DISPLAY.

Any better ideas please?
