When I was a kid, I used to sit in front of the computer and draw up concept cars on Microsoft Paint. It was, and still is, a very primitive application, but it was simple enough for me to use back in grade school. I even designed the graphics for a local ISP's website on MS Paint, but that was the extent of it.
Here's someone, meanwhile, with the know-how and the skills who decided to render a Lamborghini Murcielago, with considerable detail and skill, all on Microsoft Paint. What's more is that he captured the entire process on video and uploaded it to YouTube, from blank page to finished product. Someone with too much time on his hands? Probably, but his video has been making the rounds. And remember, if the time-lapse nine-minute video has you bored halfway through, think of how long it must have taken him in real time.
