This is a Kickstarter project. Watch out for iPen, the first active digitizer stylus for iPad. With iPen, you can literally write with precision directly on the iPad. There is a small cursor that you can see precisely where you write.
Here is a video to tell you more about Cregle iPen.
And here is a video to show you how you can use iPen.
I like the precision but I don’t like the receiver. A bit bulky in my opinion. The project has already reached its targeted fund. As of this writing, you still have about 17 hours to go before it ends.
