Time travel is being over-simlpified. No, really, it is.

What a lot of people who speculate about time travel are not factoring in is absolute position. If you send an atom back in time by one second it's not going to magically appear in the same place on the planet as where and when you sent it back in time. The planet is moving! Your atom could be dropped off somewhere in space, or embedded in rock (*waves hello to the dinosaurs*). I feel like I'm trying to tell everyone the world really isn't flat.

So, some really decent time travel science fiction movies would do well to at least factor in how they send stuff through time AND transport it through space so that it ends up at the correct absolute position for that moment in time so as to at least appear not to have moved relative to its start time and place.

It's with this kind of thinking that you can pretty much debunk all claims to time travel and the theories of the same too - simply ask what mechanism is used to positionally move the subject matter.

I know, it's not exactly news at 10 or whatever, but I guess my real point here is "validate your mental inputs". Yes, it's fun to have fantasies, but note them as such instead of going psychotic.

Speaking of psychosis, Reuben's video "Is the Internet Watching Us? Or Are We Just Crazy?" asks about the Truman Show delusion - though not about advertising - reminded me that targetted behavioral advertising is not mentally healthy for us. If it picks up on an interest towards something that affects mental health and feeds us more of the same it's simply going to make matters worse. Individually and I dare say globally (once critical mass is achieved).

So, VALIDATE YOUR MENTAL INPUTS! Predictably, I'd imagine we'll see a bunch of security firms making mental content firewall appliances in the near future - simply configure it to what kind of mental health you're prepared to live with and begin surfing the Internet.

Probably the best way of viewing the London Eye on a web site is interactively, simply because of the sheer scale of the Eye. If you zoom out to see the whole then you lose the detail and if you zoom in, you lose the whole.

The London Eye web site now gives you the ability to explore the London Eye using Microsoft Live Lab's Photosynth.
