Aside from just bending the light around a subject, bending light along other paths is also useful.
1) Bend light from one place to another to cover over something. This is sort of like the clone stamp in photo-shop or paint.net.
Example: An invisible person standing in the grass, dirt, or water displaces the surface with a dent in the shape of their footprint. To correct defects in the illusion one might bend light from a nearby patch of ground to cover over the part of the image where the feet were.
2) Bend light to make something look like its in a different location.
Example: Someone is in a fight with you. You bend the light a little to the left, so everything looks shifted over. Now every time they aim at you they miss badly.
Example: You are afraid of snipers. You routinely bend your image so that an ordinary person could never get a good shot.
This is accomplished by bending the light in a vortex or swirl pattern. In the figure below you are at A. Light images W, X, Y, Z come out from A at different angles. You bend them all slightly clockwise. Now observers O1, O2, O3, O4 (instead of seeing your true image at A) see images I1, I2, I3, I4 instead. To each observer you will appear to be in a slightly different position, but none of them will see your true position.
Of course since you are smoothly swirling the light you are really generating an infinite number of illusions, each at slightly different angles. The great thing about this trick is you don't have to know where the observer is for it to work, and it works for infinitely many observers. Each trick has its weaknesses and the catch with this one is that someone directly overhead would still see where you were (although you may appear rotated).
3) Bend only some of the light. Now you have two images.
Example: You are walking down the street alone. You bend the image of yourself partly so that from certain vantage points it looks like there is two people.
The figure below shows how this is done. You are at A. Light images X and Y are exiting you from different angles. Ordinarily observer B sees image X but does not see Y because it is going off a different way. You take the light going through cross section P and bend it so that it is directed at B. Now B sees Y and it looks like there is a copy of you at C.
Of course one limitation is that you must know where B is in order to direct the duplicate image at them. Also an observer at D will just see you as a black hole since you stole their image of you. To avoid this, just take light from an angle that misses all the observers.
Of course you can extend this to make even more images of yourself (or anything else for that matter). In the figure below, you are at A. Light images V, W, X, Y, Z exit you from different angles. Normally observer B only sees image X. You take images V, W, Y, and Z and bend them towards B. Now B sees copies of you at A1, A2, A3, A4. When they look around, it now looks like there are five of you. Note that each copy looks a little different because its from a slightly different angle.
4) Bend light to make something look different.
Example: You want to look taller, so why not.
