The computers in Jurassic Park is what got me into programming when I was young. I saw their 3D weather overlay when the storm was approaching and thought "THAT IS IT!". I was 8 years old at the time.
I was determined to learn and create that system - I started learning C, so that I could open and close files. I learnt OpenGL so that I could create the 3D scene. I learnt socket programming so that I could download weather images from the NOAA.
It took me until I was 15 (I was totally self taught and it took me a while before I could learn all of the vector / matrix math myself) but I ended up building it! I made a program in C that downloaded the weather jpg, cleaned it up (removed noise, removed the NOAA logo, smoothed out the clouds) then generated a heightmap in OpenGL, and made a fly-over.
I wish I still had the code, it's sitting on my old computer at the Farm in New Zealand :<
