What a great example of the Baader-Mainhof-phenomenon [1]. I recently found out how easy it can be to create nice-looking crystals at home, and now it seemingly follows me to reddit and hackernews.

I can heartily recommend this website, especially the different kinds of salt crystals, as they are non-toxic and can therefore be handled by children, if you have any.

I wish there were a proper aggregator of sites like this, Ian's shoelace site and all these other informative websites of different hobbies without the fluff present in reddit and the like.
