Sensible Units – Afraid of the onslaught of metric? Then measure length in albatross wingspans or weigh in terms of female lions or CRT monitors with this fun little website.

Enigma – If you’ve an interest in cryptography, this little website allows you to use your very own Enigma cipher, and provides an inkling into just how complicated the mechanism can really be.

100 Best Last Lines from Novels – How great can a last line be? I’ve read some of the works on the list and can’t say any are particularly memorable, but here’s an arbitrary list of the top 100 anyway. (PDF)

The World’s Spookiest Weapons – Starting with the A-bomb and working through mind control, crowd control and animal manipulation, this little list illustrates some of the craziest weapons designed or researched in the years since the last war.

Boxhead 2play – While away some moments (hours!) with this mad flash-based zombie fest. Can also be played cooperatively or in deathmatch mode from the same machine.

Is black the new green? – Do websites with black backgrounds use less energy than bright ones? The team from Dialogue Box tackle the issue of green web design and attempt to explode the myths surrounding energy usage and website colours.

Ten stupid ideas that earned a million – From pixel advertising to vegetarian wishbones, through HIV-positive dating and glasses for dogs, here’s a list of some of the most stupid ideas to have earned a fortune for their creators. (Russian)

Spheers – Fancy downloading your brain? Alright, that’s not quite the idea, but spheers.com, currently in beta, seems to be offering a way of keeping tabs on all that digital information which passes our eyes so we can come back to it later.

This includes videos available on a number of popular websites (e.g. YouTube, Metacafe and the like).

ControlC – This website provides a way to save a copy of everything its users ‘copy’ on their own machines, as a way of safeguarding against losing links and information they accidentally overwrite. Not sure how this works with files rather than text being copied, but it claims to be compatible with most major operating systems.

Visible Body – A fascinating look at human anatomy. Free 3d model illustrating the various systems of the body. Sadly currently only works with Internet Explorer.

What Should I Read Next? – Rather limited in scope, it simply does what it says on the tin, suggesting further reading to entered titles.
