Hi Sander,
yeah, representing data is more of an art than a science and I am not particularly good at that. I think it's crucial for story-telling with data, but it's difficult to get right.
Regarding the GPU issue: I am also on Mac, but the external Bizon Box was a Game changer for me. I have a couple of them and they work really nicely. One of the examples in the documentation runs a day on my CPU and in just over 3 minutes on my GPU. I'll try to post some benchmarks and explain how to set it up in one of my forthcoming posts.
Yes, I have been posting a bit. I have more things in the pipeline, but it often takes time to get the ok from the sites offering the data etc. I'd also live it if one could embed external videos into the websites. Sometimes it takes quite some time to "get the videos small".
You always have visually stunning images in your posts and indeed use very sexy code to get there. It's vwry nice to look forward to some stimulating distraction every time you post something!
I am looking forward to reading from you,
Marco
