Gradientor by Rodolfo Fanti is not just a great little tool, but an excellent example of a very simple and friendly user experience – which results in being a joy to use. Who doesn’t love a gradient. Change your browser window to suit, return to change colour, mouse position determines gradient position, scroll to change size and then use the spacebar to copy the CSS. Usually these sort of tools have fiddly onscreen dials, inputs and volume type bars, this solution is far more intuitive and enjoyable to use. Artistry, well done Rodolfo. And what a great name – it’s got He-man Skeletor vibes – pixelshiftor?
