Two-torus T² picture

    Hi, I can't find any picture of a two-torus T² in the net after much searching. Does anyone have a link or can draw what it looks like? Thanks.

    oh. so it's just a donut.. I was thinking of many dimensional donuts...

    if anyone has links to videos which show clearly how complex topologies like 6 dimensional Calabi-Yau can be ricci-flat, pls share it so it can be appreciated visually... thanks.

    The standard embedding of T^2 in R^3 is of course not flat. You need to consider it as a product of circles in R^4 for that.
