Just went today and I didn't see the mosaic wall, must be a temporary activity, but there were other building areas around the park including a DREAMZZZ themed one, Build + Test and Model Builder Experience. The eateries and other activity centers around the park are cool to know - I did see The Castle on the way in and would like to visit that sometime - and it's been years since I went to RoundOne in Exton, PA but a strong recommendation from me.
Had a wonderful couple of days with family and our grandson had a great time!
Next trip will be even better
