As well as writing features I also write reviews for Tap! and thought I would share them with. Back in issue 4 I reviewed the brilliant Inkpad from Steve Sprang (creator of Brushes). Inkpad is a fantastic vector illustration app for the iPad. For those not in the know, vector images are made using shapes and lines to create paths, rather than colouring in pixels, and these paths can then be manipulated using anchor points to create precise shapes with defined edges. These are perfect for creating logos or technical drawings, as they can then be scaled in size easily without any loss in quality because they are based on mathematical data rather than on pixels.
