Craig Ward

A typographer  with really cool work. Many of his works are collaborations with other people (for example the Processing works). 

Art+Com

I didn't catch this one from the begining, so I don't know the name of the presenter. I already knew some of their work (for example the kinetic sculpture for BMW). He presented Mobility which is a pretty interesting installation using prosthetic hands and mirrors to form projected light messages. He also spoke of one work from a student of his which I didn't know about: the Image Fulgurator. This is an awsome project, that basically consists of a device that projects a message into an object when someone takes a picture of that object (it basically detects the flash from the other people's camera and projects the message for a brief period). It's almost impossible to detect and he's made some impressive interventions with that. 

Grady & Metcalf

Two american designers that publish the Lemon magazine.

Non-format

Another typographer with some cool work and very good presentation skills :)

Julien Vallée

A motion and design artist that likes to work with real objects. I liked specially the process of his work (for example the cover for the computer arts magazine or the Danse Dance video)

Multitouch Barcelona

I was a bit disappointed with this one. Their installation (at least I think it was theirs, there was no identification that I could see) was not very interesting (you could basically adjust some graphical elements - moustaches, hats, etc - over a live feed image of the audience in the main room (I think)). 

Daniel Shiffman

And, of course, the Most Pixels Ever workshop.
