One of the most intriguing sites with interactive media is http://weavesilk.com/
This website just like many others of its kind allows interactiveness to seep into the user’s experience. After creating their own custom picture, the user can then save their picture. Although this website and its concept might seem simple, it still manages to give the user a sense of ownership and originality into the things that they make, which in my opinion is the most important for an interactive website.
This website is the previous website and more. It is a collection of various small interaction-based arts and games that allow the user to indulge in various different activities. This gives me a feeling of a gallery, every piece an art in its own way.
