The internship program demonstrated the importance of involving the users in the development process, and the value of creating educational environments where young developers and designers can experience and learn about a user-centered process and its results.

"Eu estou emocionadíssimo e sem palavras com o quê estou vendo aqui. Os widgets, por conceito, são aplicativos simples. E estes aqui não são. Pelo contrário, as aplicações desenvolvidas nesta residência são complexas e, o que é melhor, com alma coração e corpo. Parabéns a todos envolvidos” Miguel Lizarraga, sponsor
