The contraceptive pill.

And what about porn? Likely a far more important invention in the slashdot community.

I will now officialy reveal to you all that the greatest invention of the century has been (drums...) Sinclair C5 electric tricycle :

• cheap (5*zx spectrum+)
• environment friendly
• low power consumption (but if you're slim it helps even further)
• immensely safe (provided everyone switches over)
• lightweight (esp. without the battery in it)
• cool looking (no? OK maybe not!)
• efficient beyond belief (20miles/battery downhill)
• ultrafast (particularly on a steep slope)

Clearly ahead of its time (although behind every other vehicle on the road including golf buggies). Still can't get over why it hasn't stormed the world the way speccy did :o)
