Bixelangelo is a small paint tool that records your illustrations and stores them as sketch maps. These maps, instead of containing color information, save the times when each pixel was created. Having everything recorded with a specific time frame allows the sketch to be played like an animation.
Due to the visual impact, this is very useful for graphical presentations. Unfortunately, only one color can be used, which is a serious limitation. Another limitation in editing your sketch is the lack of an erase option. If you made a single mistake, you have to start everything back from square one.
For sketches enhancement, Bixelangelo offers also a couple of very helpful features. A picture can be loaded in the background, so all you have to do is trace the lines from it. If the drawn lines look a little "trembling", the program will automatically enhance them into good-looking, well-connected curves. The drawings can be saved as .png bitmaps and also as DirectX effect files.
Overall, if you are not a Picasso, and you need a fast and reliable application to make a good-looking monochrome sketches, Bixelangelo is what you need.
