Inkscape is an Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format.

Inkscape supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more. Inkscape also aims to maintain a thriving user and developer community by using open, community-oriented development.

Design is a suite of web-design and development assistive tools which can be utilised on any web-page. Encompassing utilities for grid layout, measurement and alignment, Design is a uniquely powerful JavaScript bookmarklet. Click on the bookmarklet to run it and then you can load each individual component by simply clicking on the icon representing that component in the Design control panel.

Design features the following components:

• Grid - overlays a highly configurable layout grid over a web-page. Grid can be set to match any set of dimensions, allowing easy development of CSS layouts in the web-browser.
• Rule - displays rulers on a page, with all the expected features of the rulers found in a desktop design application, including guides which snap to block display elements and origin location control.
• Unit - allows measurements to be made between any two points on a web-page, giving basic information about each of the points clicked on, and drawing a line on the page for the measurement.
• Crosshair - draws a crosshair cursor on the page to assist in layout alignment. Cursor information is also presented in a tooltip.
