So, I'm assuming that we're all familiar with Nidhstangs, or Nithing Poles.
If you aren't, here's the wiki, you lazy bastards :
http://en.wikipedia.org/wiki/Nithing_pole So, here's a concept :
Why not set up a series of linked "nithing poles" across the country (country? World?) directed at central locations of...how should I say this ..."concentrated Reality"? Instead of focusing on the harmful aspect, just direct a sort of guided Chaos-current into...wherever.
Basically, set up some powerful Chaos totem-pole/ projectors, and charge them all and fire them all at the same time.
Side-idea...
We could also use the same concept to build a Working for next year's Chelseanacht .
Those that can't actually make it to the gathering in New Orleans can build Nidstangs and fire them towards Nola at the appropriate time.
