I had some time on the weekend to do some coding, so I “finished” a project I’ve spent a few nights playing with.
The idea was to pull together some visualization of the twitter sample feed. A work colleague (spud) suggested a heatmap where the points fade out over a few frames. And here it is: http://twitterheatmap.com/
I’ve got an EXE running on an EC2 micro instance dropping XML files of all the tweets into a folder. Another EXE fires once a day at midnight UTC, generates the JPGs, creates an AVI (with VirtualDub), and uploads the video to youtube. The data you see live right now is a bit flakey – displaying a fail whale where I don’t have any data.
Grabbed a lot of handy code off the net to build this:
- Day and Night Map – code to draw the day / night terminator
- Creating Heat Maps with .NET 2.0 (C#)
- jQuery youtube playlist plugin – youtubeplaylist | Gecko New Media Blog
