Partial or cut capos are great fun. You pop them on the neck and it opens up a whole world of opportunities without the bother of having to retune. They're called partial or cut capos because it's like you have chopped bits off a full capo, so they only cover a few of the strings!
For example, put a 3 string partial capo on the second fret covering the A, D and G strings to make an Esus chord - which is like being in DADGAD tuning but a tone up! Also on the second fret, but upside down and covering the D, G and B strings gives you an A chord, like being in open G tuning but a tone up.
But if you want to get REALLY creative there are lots of other places to put the capo... here are some great videos and resources so you can get creative with a 3 string partial, which you can purchase from here!
