Now go outside and look at the sky.
I've personally found 3D rendering never boring, it just always eats up way too much of my time... I'd love to do more of it again, but it's far back in my list of things to do. Oh well.
And here's a guy who really seems to love rendering - for a year now, he created a new 3D scene almost every day on his site, Boring3D.
His work shows a lot of quirky humour and unsuppressible creativity and is guaranteed never boring!
