Imagine a world in which every single person on the planet is given free access to the sum of all human knowledge. That's what we're doing.

The very existence of Wikipedia is proof that there are more people in the world wanting to build than to tear down. Were that not true, vandals would have overwhelmed and destroyed us years ago.

I believe knowledge should be beautiful! If you need any help with diagrams just let me know and I'll see what I can do.

My main focus of work lately has been the Group Testing article, which recently passed its GA review. Next I'm hoping to take this article to featured, so any suggestions or feedback is welcome.

I am also currently recording a spoken version of the Earth article. You can find my script here.

Gallery

Here you can see most of the graphical work that I've uploaded to date (almost entirely SVGs) in reverse chronological order. Note that many of these are vectorisations of previous works. In these cases, click on the image to find a link to the original author. I do all my vectorisations by hand to ensure the best quality (compare this and that to see what I mean: one tenth the file size, incalculably better quality). For a full list of uploads see my upload list.

Vector bloom

Some say that as long as you keep dreaming, your hard work might one day bloom into something beautiful

Vector Bloom is an ongoing initiative of mine hosted once a month. The idea is to draw 10 or more diagrams (vectorisations are permitted) on a single day. Then I'll add comments on how 'the bloom' went.

Update: This initiative has been canceled. Contrary to it's original aims, Vector Bloom ended up decreasing productivity. This is because it incentivised 'saving' vectorisations for later (so I could tackle them all at once). This then created a barrier: if I wanted to do a vectorisation, I would be committing myself to doing 10, or I'd be wasting the ones I did. Anyway, I'd like to find some other way to increase my productivity in this area, but until then, I'll just be working sporadically as usual.

Bloom 1 (14/2/2017)

This bloom was dominated by 'arrow style' diagrams, and I feel like I learnt a lot about easily placing text. I finally started using one of Wikipedia's available fonts for the first time (letter placement issues be gone!). I also drew some icons that we're hoping will make it into a new Wikiproject banner template. All in all it was a pretty successful bloom, though the uploading process to a lot longer than I had anticipated.
