I would love to use hand drawn graphics in my presentation, but I never got to drawing and sketching on a computer. Any tools without a direct screen feedback loop (the mouse, drawing pads, and even the Wacom Inkling) simply do not work for me, and I think a screen like this are very expensive and generate additional clutter in my workspace.
The iPad could solve this, because it has a touch-sensitive screen. As a result, hundreds of drawing apps have popped up in the app store. Drawing apps are different from note take apps. The latter require wrist protection, a good way to organize notes. Drawing apps require brushes, color, pens.
Like with writing apps, most drawing apps come loaded with features that just confuse me.
Hence, I was happy to discover Paper by 53, a minimalist drawing app (one of the readers pointed it out to me in a my recent review of iPad note taking apps). Paper just cut down the drawing tools to the bare essentials, and the result is actually good I think. The app is free, but this version comes with one drawing tool: the ink pencil, if you want to get a pencil, a marker, a pen and a paint brush (water colors) it will set you back $8 in in-app purchases.
The pencil is the tool I actually use most. There is a big drawing problem with the iPad screen: it is not pressure sensitive, and varying stroke width is the key feature what makes writing with an ink pen so great. Paper solved this with adjusting the stroke with depending on your speed as you move the pen over the screen. More confident, fast strokes, will appear bolder. (The pen tool works the other way around, moving it slowly creates heavy ink, moving it fast produces a thin line).
I love the simple cartoon style sketches that this app produces, and I am looking out for a first client situation where I can try out a cartoon-style presentation (like the one below) for real.
