Please give us a brief bio of yourself.

I'm a Spanish interactive designer & developer, currently based in London and working under the studio name of carlosulloa.com.

I've always been passionately involved with interactive entertainment. During the 90s I worked on various areas of the game industry, including PC and PlayStation development at Psygnosis and Sony.

In 1999, I moved into Flash design and worked for OgilvyInteractive in Madrid, DoubleYou in Barcelona and Hi-ReS! in London, among other design and advertising agencies. During this time, my work evolved into the fields of graphic and typographic effects, motion design, interactivity and 3D.

For the last two years I've been developing Papervision3D, a realtime 3D engine for Flash. Released as Open Source on December 1st 2006, it has been quickly adopted by developers and agencies worldwide. Papervision3D is now developed by a team of 8 and tested by more 2,500 people.

What do you do for inspiration?

I find inspiration mostly in music, but also in games, motion graphics, architecture, nature... But best ideas usually come when walking in the park or along the canal.

Please list 3 of your favourite sites.

I love these three Papervision3D sites, good examples of experimental work as part of an advertisement campaign.

Canon EOS 400D. An immersive experience that combines navigation and exploration.

REC YOU. Great concept and superb creative and technical execution.

Rhythm of Lines. A very ambitious project that breaks new ground among web experiences.

What do you regard as being your biggest achievement?

carlosulloa.com is the culmination of many years of work and research. It gives me the opportunity to work for clients that enjoy my work as much as I do building it.

On a project level, I can't ignore Papervision3D, certainly the most successful project I've ever worked on.

What software could you not live without?

Directory Opus on the PC (and the Amiga).

What projects do you have in the pipeline?

I want to continue exploring the possibilities of 3D navigation and hope my next projects are based around this.

I'm also prototyping a 3D driving simulation but haven't found the right client yet.

Who do you rate as being the top 3 design companies?

Hi-ReS! the most creative studio I've worked at.

North Kingdom - simply love their work.

Erik Natzke, a constant source of inspiration.

But there's a new generation of web designers coming through, people like Mathieu Badimon, Masayuki Kido or mediosyproyectos.

What effect on traffic do your new designs have?

Since my work is very interactive, centred in the user experience, it tends to spread virally, attracting all sorts of people.

Who is your target audience?

We aim to deliver a compelling experience to every user, regardless of the target demographic.

What did your very first site look like? Is it still online?

My first site was the first version of my portfolio Noventaynueve.com 1.0. It's still online and can be accessed from version 3.0, which also was the debut of Papervision.

Have you written any books, if not do you plan to?

Right now I'm focused on my commercial work and on Papervision3D development, but in the future I would love to complement my conference and workshop work with writing.

What was the toughest thing you ever did with Flash? How long did you spend on it? Is it still online?

During the development of Papervision3D I faced many programming and mathematical challenges. After all the hard work I'm very happy to see what people are doing with it.

Do you think Flash is here to stay?

Until something better appears and users adopt it, there's no better option for delivering interactive content on the Web.

When your company was just getting started, what did you find was most effective for getting new clients?

We believe that building a good portfolio is the best way to attract clients.

How have you learned so many Flash/design skills and techniques and can you offer any advice for newbies?

Always try all the options you can think of. Don't leave any route unexplored.

What is the most expensive thing you have bought in the last week?

The most expensive bike lock I could find, after my new bike was stolen on its first day.

Any parting shots or pearls of wisdom?

It has been a privilege, thanks very much.

It's my pleasure. Many thanks to the FWA.
