Suffice to say that I did not appreciate Let the Right One In. Despite liking little nasty books, I am definitely not a horror reader. It was also very, very wordy. From one of the programmers behind Etsy, I give you Orbital B. It is "a collection of particles operating on one simple rule: choose another particle in the system and orbit it with a fixed radius at a constant velocity." In other words: you get to play with little aplets and create really gorgeous art vaguely reminiscent of Umberto Boccioni (Italian Futurist whose artwork I admire).
If Orbital B isn't your thing, how about NewScan. You select your favourite newspapers and, hey presto, you get to read the news. It's pretty if a bit impractical.
Finally, some things once seen cannot be unseen; some things once heard cannot be unheard. So, keeping that in mind, here is Limahl and His Swing Orchestra. You can thank/threaten me later.
