Introducing Slixed: An online drawing program which allows you to create Commodore 64-esque pictures with the C64's glorious 16 color palette. You can choose to create a new drawing from scratch, or load an image (in JPEG, GIF or PNG formats) which can then be edited in either hires or multi-color modes. Once you have an image worthy of hanging in the Louvre, you can save it off in PNG format for posterity or for later editing.
The program is currently in alpha, but it's certainly quite usable. One can only imagine what great features may be coming down the pike: Saving and loading in native C64 formats.. editing the various interlaced (high color) formats.. exporting images to assembly includes (for coders).. the skies the limit.
Just one more great cross platform tool to help modern C64 developers create new games, demos and art.
