Responsive Solid Icons
That is 100 distinct icon concepts with 3 different size and style versions, each of them containing various amount of details. That's 300 symbols!
The icons are designed upon 3 different grid sizes: 16x16, 32x32 and 64x64, each of them featuring different amount of details. They are crafted as vector shapes, so scaling them to your own needs is not a problem. Just make sure you keep the progressions of doubles (128×128, 256×356... ) in order to get that super-crisp look.
