<p class="style1">UOVO was founded by two hard working, creative guys who shared a passion for entertaining interactive design. They soon figured out that if they joined forces they could give their clients the whole egg - a one stop production house, bursting with creativity. Concept development, <a href="http://www.uovo.dk">web games</a>, cartoons, mobile games, e-learning, interactive web toys, <a href="http://www.uovo.dk">illustrations</a>, animations... to say it simply, we make fun stuff. And we love doing it. And that's important, because it means our clients get 110% from us. <br />
<br />
UOVO is a professional production house, but our true strength lies in our creativity. When a client brings an idea to us, we don't just put it through a machine. We think about it and think about how we might make it better. We take pride in the fact that we don't just know how to make things work, we also know what works. Take a look at our Cases to see some of the eggs we have cracked.</p>
