I've got 50 free passes to the SIGGRAPH exhibition floor, you can grab one if you like.

To get one, go to http://registration.expoexchange.com/ShowSIG071/Default.aspx and then choose the Attendee option. Scroll to the bottom of the page and click the Exhibits Only selection and enter Tri1188 in the "Exhibits Only Code" box.

That will get you a free "Exhibits Only" registration that will allow you to enter the SIGGRAPH exhibition floor.

There is also an option to upgrade to "Exhibits Plus" for $40, which gets you access to some of the other parts of SIGGRAPH other than the exhibition floor as well, like some art galleries, etc...
