The roses looked about the same to me, but the gif will load much faster. The left one is the jpg.

This one is only 428 colors, so I did it as a gif. I used the sunburst gradient, inverted, with the autumn color scheme.

Since this one has so many colors in it, I saved it as jpg, 30% scale, 35 degree angle. Smearing gold.

Okay, here's several gradients. Wild enough for you?
