I bought TypeDrawing last night from the App Store. Today, it rained pretty much all day, so what did I end up drawing? Something to do with umbrella and rain, of course!
The software is quite interesting. You type a sentence, choose a font, and a background, then as you draw with your finger on the iPhone/iTouch, the text is drawn out. In my case, the face was drawn from the phrase "Qaptain Qwerty" - if you don't know who that is, Google it. The umbrella of course is made from the word "umbrella". Lastly, the rain drops etc. came from the 3-word nonsensical sentence "rain shower drizzle", which almost accurately reflects the weather today. Well, at certain time of the day, we actually had downpour or torrent.
I've discovered that if you draw slowly, the types are small. Likewise, if you draw fast, the types are large. Not an easy thing to adjust to, but it is fun to play with. Perhaps because of the vector graphic nature of the program, there is no eraser tool, you just use the Undo button to work your way back, one line at a time.
