I'm not usually post about Kickstarter projects but VGC Illustration seems like an interesting open source vector illustrator program.

I love Inkscape for my vector graphics illustrations but judging from the information VGC Illustration could have some advantages. Perhaps most importantly that Freehand sketching and that can be shapes can be connected which should lead to quicker design. BTW: The advertised Python console reminds me of a similar feature in Dust3D, a FLOSS 3D modeller.

To get an idea what VGC Illustration is all about you can already download VPaint, a prototype: https://www.vpaint.org/#download

'...VGC Illustration is proud to be publicly developed on GitHub under the Apache 2.0 open source license. Indeed, I believe that source code is knowledge, and I believe that knowledge is meant to be accessible to everyone for free. I also believe that users should have the freedom to modify the software they use.'
