Inkscape 0.45.1

Inkscape is a scalable vector graphics editor, similar to Adobe's Illustrator. Scalable vector graphics (.svg files) are images that keep their "resolution" regardless of size, which is awesome since conventional pictures like JPEGs and GIFs get all blurry when enlarged.

Inkscape works a lot like Photoshop/Illustrator/GIMP, with an easy to use albeit slightly cluttered interface due to the multitude of windows instead of a master window. However, it is arguably further along than the GIMP in terms of professional usability. In fact, I'd say it's a decent substitute for Illustrator for general use.

Then again, I'm not a graphics designer. But I LOOOVE the calligraphy pen.

Play around with it, check it out. It's good for designing website banners and t-shirts at the very least.
