Today the girls drew some great pictures on the Tesla touchscreen using the "MacPaint" and even posted one to Tesla. The updated software today also added more features to the Games in the computer and Sentry Model camera. The upcoming Version 10 software has some amazing new features too, such as being able to watch Netflix etc from the touchscreen (TBC in Australia)!
You can convert everything you see to a format you find convenient. Give it a try!
