Something that should appeal to a lot of folks at a price tag of $2.99 — Autodesk SketchBook Mobile painting and drawing application which extends your digital sketchpad to your Apple iPhone or Apple iPod Touch. Sporting the same paint engine as Autodesk SketchBook Pro software, SketchBook Mobile offers professional-grade painting and drawing tools in a streamlined and intuitive user interface.
Although I can’t see architects designing large canvases with this tool, it is great for capturing those fleeting ideas that can end up on a cocktail napkin or the back of an envelope. This way you’ll be able to have a digital representation to take to your computer later. What a concept!
