But the app does mark thinner lines when you draw faster, giving a small but pleasing variation to line weight. The iPad screen isn't pressure-sensitive, so the Bamboo stylus isn't as sensitive as the stylii that come with Wacom's pressure-sensing tablets, which know how hard you're pressing and vary line thickness accordingly. And these marks can be eradicated with a quick swish of finger or stylus - marvelous. But again, taking a more relaxed approach made us smile at the inadvertent marks - the digital equivalent of smudging your paper. The only problem with the stylus is that if the rest of your hand touches the iPad, it can leave unwanted lines. We found that once we relaxed into the loose style required, and got our eye in, drawing with the Bamboo stylus could be an absolute blast. It's no draughtsman's tool, but the stylus surprised us with how precise it could be - and how much fun. It mimics the effect of a finger, so it feels like drawing with a big thick marker pen. The Bamboo Stylus feels like a normal pen, but with a squidgy end.

We grabbed an iPad and the Wacom Bamboo Stylus, a pen that draws on the iPad's screen, and got art like Tony Hart. Wacom Bamboo Paper is a new drawing app for the iPad, and we decided to channel Rolf Harris to test it with requests from our Facebook fans.
