I hacked together a LaTeX template for conference posters for the Wireless Foundations Center. After searching around on the web I couldn’t find a package that was (a) easy to use, (b) allowed for arbitrary layout, and (c) supported many different poster sizes. So I hacked together 2-3 other style file ideas from other people and made this template and associated style file. I’ll try and add features over the summer, but that’s a really low priority right now.
I’m using the package to make a poster for tomorrow’s day conference at Stanford and it’s going pretty smoothly, so I think it’s reasonably usable.
