Problem description:
Hi guys... another question about DM's capabilities here. Is it possible to create distortion effects over the top of the client's map?

I'm thinking like a ripple effect or a swirl that makes the map tiles look all weird without actually editing their icons (or how they look to anyone else).

I guess an example would be like in Amnesia, how the screen starts to crawl if you get scared enough. That kind of overlay effect.

The only way you can do it is through modification of /icon objects and usage of /image which could be resource intensive. There's no built-in way of doing this.
Might be worth it to use another program like Gimp or Photoshop, apply a wave motion and make a turf overlay. Or perhaps a screen image and apply it.
