Looks like a very cool addition!

Hows about adding a greyscale feature for surface depth control (front & back could be mirroed)

adding greyscale and a 'blur' tool will make possible for easy 'puffy' shapes.
looks like a great start, looking forward to see the development.

Artur, can you explain how blur could work in that sense?

Pete,

What I think Artur proposes is probably something like the way "bump mapping" works in games. Bump maps allow me to give a point on the model the appearance of being raised or lowered from its actual position, without actually modifying the geometry. The bump map is a texture which I create in grayscale, then run through the nVidia converter filter, which makes a multicolored texture.

Here's the point: In the grayscale texture, the relative color is the main importance. When I want to make a "dent" (meaning the model appears to move inward at that point), I transition from a light color to a dark color. When I want to make a "bump" (meaning the model appears to move outward from that point), I transition from a dark color to a light color. Blurring makes the transition more gradual. See this article for more information on how this works and how it is done for games.

Woo. Now things are getting tempting to try!

That's definitely in line for version 2.. in fact, I think there's a python script that needs a look-see in my inbox. :-)

There's a lot of creative ways to use this. Actually, I took a cross section of a money clip, and made a money clip yesterday: http://www.shapeways.com/model/249080/

I am with Paul King!
This Creator is very great but with a grayscale function to give a feature for surface depth control will be great!
( Sorry but I don't speak very well English gh ^^'' )

Is there something peculiar about this? I just uploaded a viola mute that is seriously less than 2.5 inches wide, and wanted to print it in steel ... and was informed that it was $636! Did something go wrong, or is this Image Popper thing a rich person's toy?
