I hid a little man.

speaking of the artport...
artcontext.net is a site created by Andy Deck. He is an Internet artist who well known and even has been commisioned by the Whitney Museum in New York for their artport site. His art focuses on interactivity, community, and politics, and is indeed created in a context; the context of the U.S. Many of his works are commentary on the current issues of the U.S. and his opinions are made very clear. He does stay away from being too preachy and instead presents his opinions in a more humorous context, with silly phrases and the use of icons and familiar computer text boxes and install windows.
One of his pieces that i enjoyed was the glyphiti project. It involves simple black and white pixel art that is gridded into square sections. the user can click on a section, which is then displayed enlarged and can be edited by the viewer. there is some pretty impressive "graphiti" on this site. I made a small addition, as i didn't want to disturb other's additions, and the project is very full. My addition can be seen in large right here: ------canyoufindhim?------>
there is also an inverted version of him somewhere else on the image.
and while you are looking, go ahead and add your own touch to the site. that's what it is there for.
that is one thing that i really like about his projects, they are very on topic with current events (usually) but are also very playful and interactive.
