The alpha version of the new HTML5 toolkit is out! News here.
NTK (the NETLab Toolkit) is an authoring system for designers, developers, makers, researchers and students who want to design and build tangible Internet of Things projects. With a simple drag and drop interface, connect sensors, actuators, media and networks with the smart widgets. Concepts can be prototyped quickly, encouraging iteration, experimentation and testing by sketching in hardware and building connected systems.
Go ahead, Drag and Drop the Internet of Things.
