# Shading in Math Mode? [duplicate]

Is there any macro or package known to shade equations in math mode like the image below?

I achieved this by using IguanaTex 1.54 in PowerPoint 2010, and then shade the text box as usual. I could use snipping tool and take snips of the formulae from PowerPoint, but I would like to make this by LaTeX directly, if possible. Is there any way to do it?

• @HenriMenke It doesn't seem to be straightforward to extrapolate from the dupe solution (which creates shadows for text in tikzpicture environment) to displayed equations? – Troy Oct 4 '17 at 3:01

This looks more like I'm drunk...
