The screenshots under the homepage introduction have been replaced by a stack of drawn pictures, one for each tool. The front card shows a tool, a sentence about it and a link to its page; the edges of the next four cards show to its right.
Click or tap the right half of the picture to move to the next tool and the left half to go back. On a phone you can also swipe, and the left and right arrow keys work too. The stack goes through every tool and starts again; it never moves on its own.
On a wide screen the sentence and link are beside the picture, which is at most 480px wide. On a phone they are below it.
