Plugin to put a featured image from last post in a page

Hi, recently I wanted to change the layout my blog’s homepage by editing the images contained within. Since in my homepage I show the 4 main categories of my posts along with an image that represents each category, I thought it would be cool to display the last post’s featured image of such category instead of a static image (and maybe even link it to the post itself)

Is there any plugin to do such a thing? I’m pretty sure I’m not the first one to come up with this idea. Anyone know of any plugin?

Thanks in advance,
