Hadn't seen this one before:

Sorry, just kidding around with Apple Motion... :wink:

Is the first part of that real?

(not as good as the still photo of the Transit across the sun, which showed the sun with what was clearly the silhouette of a Ford Transit van near its eastern limb )

Nothing real.
All manufactured in about an hour using Apple Motion. It was my first try with the software, so things will only get better...

The sun's 'surface' was created using two differently scaled semi-transparant layers of a built-in video generator called cellular. You can see it's fake: it changes too fast compared to the real sun (this was however intentional).

Venus and the smiley are a very simple two-layer photoshop-file, with the second layer fading-in during the first bounce. The graphic is affected by several so-called 'behaviours': 'Throw', for the motion sideways; 'gravity'; 'drag'; and 'edge-collision'.

Oh, I thought you might have taken an existing movie of the transit and just doctored the end somewhat

I might have thought the same 8)

However: Motion is an extremely cool piece of software, and besides Celestia the only sensefull use I've found for the quite respectable GPU in my pobo (I don't like gaming). Motion takes (lots of) advantage of a powerfull GPU: most of the effects are actually programmed shaders. The application will not run on a Mac with a GPU without programmable shaders.

Throw it to purgatory?
