Anyone who drives a bycicle knows that the rear wheel follows a smooth path compared to the front wheel. So this image is easy. I guess there might be more tricky images. A straight line for instance ;)
Currently I have 267 tabs loaded in Firefox and in any given day I might load 50-100 tabs which I devote around 2 hours in a day to reducing down to around the 250 mark. I had about 420 tabs but in the last couple of weeks I have actively reduced them to the essential 'must-read' one day. http://imgur.com/1K4s6MP (this was a couple of days into my drive to reduce my tabs). Oh and I use firefox on linux. Hands down the best browser I have ever used.
It's really tough to say, I've been working on it off and on for a few months. But I didn't really keep track of the time spent. I'll probably put it up on github when finished and see if anyone wants to rip apart my solutions and/or contribute better ones.
