Eight-bit (pixel) cursors. Pixel, and evoking some nostalgia, design execution in the form of such pointers, no doubt, will find its fans (and probably even a large number of them). At least a good technical performance (this includes nice colors, support for functions such as scaling for high-resolution screens) give this great guarantees, which will only be improved by the author over time through updates.
Otherwise, it is a simple and, in principle, not a large set.
