Hi @germansailor. These posts are really cool. I've never seen actual 3D art exhibitions. As one of the editors for @steemitworldmap’s daily #traveldigest, I would love to see these posts pop up on http://steemitworldmap.com. If you're interested, simply go to the website, click on code (down the bottom) and add a short description. It will then generate the code you need to copy and paste into your post (not the comments) to have it show up on steemit worldmap. There’s also a FAQ section if you get a bit lost.
You can find out about the project here:
