I remember our family got a 286 IBM-compatible PC when I was maybe 9 years old. It came with some pre-loaded software, including something I think about from time to time, which was a DOS program that displayed a rotating, photorealistic (possibly ray traced?) can of Jolt cola.

I don't *think* it was a demoscene type demo, I think it was like, a commercial graphics demo. I went searching for it but couldn't find it. Anyway, it mesmerized me to see something photorealistic on a computer screen
