Convention Stuff and geeky events

Have conventions to go to...  Pondering costumes.  Advice solicited.

Also interested in geeky stand-up.  Anyone want to come?

Satellite 3.

The theme is Mars.  The obvious Martians themed costumes are Marty the Martian, Martian Manhunter, generic green man, and Mars attacks, all of which are a little too much effort.  I don't really have time or patience to create a costume. 

Eastercon.

Don't think there is a theme here. 

Brighton appears to be having a Science festival. 

Anyone fancy coming to see the Spoken Nerd thing with me?

Or one of the science of magic things where Trez seems to be performing.
