Microon BMP image creator uses Flash and Asp to generate little BMP images (little because of the dimension). Click on matrix to start painting, click again to stop. Choose the color. Finally you can save your BMP (real) file, and see other users files.
The technology is fully scalable, but with a greater number of "pixels" to be painted Flash becomes very slow. Sorry, but is not a my fault. :)
1/29/2002: Fixed 1 bug for then "new" button: it caused an error when it was pressed and then saving image.
