Experimenting labels which follow your touch in @solarwatch. Laying them out correctly is going to be hairy. Open for ideas and suggestions.

I’ve been working on the yearly overview for @solarwatch today. This screen has potential for a lot of astronomical data visualization. It will be fun to design it.

I’m very proud of my three friends who finished the Berlin Marathon today. It was so inspiring to support and cheer for them!

If my math is correct, we’d need to forest 3 times the whole area of Brandenburg to offset the CO2 output of Berlin.

Apparently one acre of new forest can capture 2.5 tons of CO2. That is 6.2 tons per hectare. http://urbanforestrynetwork.org/benefits/air%20quality.htm
