This was for a company called thinktecture. They provide consulting services to software developers and architects - help them understand new software-development technologies (languages, frameworks, databases...) and use them in their projects.
They work with cutting-edge technologies, usually 2-4 years before they reach the mainstream software developers in their market.
The technologies they use are Microsoft's .NET Framework, HTML5, JavaScript, AngularJS. Clients develop software for desktop systems, iPad, iPhone, Android and Windows 8.
They wanted a t-shirt and coffee mug design for an Europe's largest JavaScript conference they would be sponsoring. Here are my entries to both projects:
Thank you for watching! :)
