Excalidraw
Virtual whiteboard for sketching hand-drawn like diagrams
Excalidraw, the virtual whiteboard app for sketching hand-drawn like diagrams, has come a long way. With the remote work becoming the status quo, Excalidraw was able to show its true potential and we’ve come to a point where over 100K people have used it just the last month! While it has been extremely successful as a free open source project, the biggest source of complaints nowadays is around adoption within companies: How do you share diagrams with your co-workers easily? Can your company depend on the service for live collaboration? Is your data secure? We’ve thought long and hard about how to make it happen in a volunteer-based open source model but haven’t found a great solution. So we decided to build a company around Excalidraw with the first product being Excalidraw+. With account-based access you can rest assured only the right people will have access to your data, while still retain the ability to share specific drawings with outside collaborators. -

Current development is located on https://bitbucket.org/bmorel/autorealm . Howerver, older repositories are still here in case someone would like to consult them, and to allow easy access to algorithms they might contain. -

PureCSS Francine
HTML/CSS drawing in the style of an 18th-century oil painting
purecss-francine is a remarkable artistic and technical project created by Cyan Harlow, demonstrating how complex digital illustrations can be achieved using only HTML and CSS, without any JavaScript or images. The artwork, titled Francine, is a detailed portrait crafted purely through CSS shapes, gradients, and layering techniques. It showcases the expressive potential of front-end technologies and serves as both an educational example and a piece of digital art. The project emphasizes precision, creativity, and the boundaries of what is possible within web standards. Every visual element—from facial features to textures—is rendered using handcrafted CSS properties, illustrating advanced concepts in styling and layout manipulation. As a result, purecss-francine stands as a powerful example of CSS mastery, inspiring developers and designers to explore the artistic capabilities of code. -

Assisted dRawing toOl
ARO helps physically disabled students to create mathematical drawings
ARO has been developed to assist physically disabled or injured students who cannot create mathematical drawings on paper. It is intended to make maths up to Key Stage 4 more accessible. AQA has agreed to its use in a GCSE maths exam. Anyone who can use a computer with a mouse to access the internet should be able to use ARO. The processes required mimic those of on paper drawing as far as possible. Possible applications include: Graphs of straight lines and smooth curves Compass and ruler constructions Scatter graphs Stem and leaf displays Box plots Histograms Pie charts Simple diagrams. The structure of each drawing is built from individual components which can be placed on the drawing grid without great accuracy. Each can then be positioned exactly using onscreen buttons. The ruler and the protractor can be aligned with any straight line. Drawings can be created on imported background bitmaps. The author was a mathematics lecturer at Plymouth University. -
