Scientists in Birmingham have been designing an invisibility cloak (more precisely, a lump of crystal) that can make objects seemingly disappear. The cloak bends light to obscure small objects behind it, making it seem invisible, while also appearing to be flat. So far, the largest items that it can conceal are things like paperclips, while the cloak itself is roughly the size of a paperweight, much larger than what it is concealing.
Conceptually, a seven-meter wide cloaking crystal could by used to make something like a large dog invisible. So far this is the biggest enhancement in invisibility cloaking technology, and the technology is still improving.
You can see a video of the device in action, making a paperclip turn invisible!
