A new online drawing tool Grid Paint was opened. You can draw using various types of grids (squared, triangular, hexagonal). Drawing in Grid Paint is something like pixel art, but in pixel art you have only square pixels. Here you have also triangular or hexagonal pixels. Moreover, every pixel may be flat or have concave or convex shape like diamond or jewel, which allow you to create peculiar images.
You can share your images with friends on Facebook or Google+ or download them in PNG or SVG format.
