I will provide:
1 laptop on which the performance runs
Iwill need:
1 network connection (Ican try to provide this with mobile phone or, if it's not available, I'll prepare some offline data to "fake" a connection :) )
1 or more projectors (VGA or adapters;multiple projectors fed through splitters;i can also do it nicely with more computers which Iwill bring and take care of synchronizing if you say that Icould have more that one indipendent output available)
1 sound system (the performance will output a basic stereo line out, pin jack)
