OmniDazzle alternative for modern Macs? Is there any tool that runs on current Macs providing a flashlight effect to highlight a portion on the screen?

In the past I've used OmniDazzle to create screen casts using this effect.
On recent OS X versions it doesn't work any more, though..

Any hint appreciated!
Yes, I'd recommend Mouseposé. It's very similar in spirit to OmniDazzle but works with recent versions of Mac OS X.

One nice feature is that if you pause for a little bit, Mouseposé will expand the highlight from the pointer to the whole window.
