24. Photo of your handwriting (use longhand/cursive!)
Not really a photo but a screen capture of writing on the iPad. I don't think I've used cursive since elementary school. For me, printing was easier to write, faster and easier to read so I included samples of both. This was done using the standard Note app and a stylus.
For writing on the iPad, I've been using a stylus made by Adonit called the JotPro. It was marketed as a "precision stylus" and though it's better than writing with your finger, the iPad just doesn't have very good resolution for writing or drawing. I hear that the new iPad Pro does but I think that it's way too big and heavy to haul around. But since I'm not an artist, this does just fine for the little bit of writing and annotation that I do. There is a newer version of the stylus but I'm not really sure of the differences.
