I came across LastGraph a while back but I love going back and re-generating my Timeline Poster. I’ve been using Last.fm since 2007 so I’ve quite a bit of data collected. This leads to a very large and detailed poster. I’m currently looking into printing this out on a whopper scale! I think several A0 posters stuck together would be pretty interesting.
It reminds me of a Canvas I created for my 21st Birthday. I took all of the album art from my iTunes Library and used an automated process to position these album covers in a Photoshop canvas. The final result was a 36 x 36 inch colour canvas featuring all of my favourite music when I was 21 years old. Each album cover was approx 3/4 of an inch square. I’ll try and dig up a photo and post at a later date.
