Item #3 is what appears to be an image taken with an electron microscope, or something like one. The scale in the lower left reads '5 micrometres' and that it's at 5000x magnification. The object pictured looks not unlike a fleck of some organic material, as its surface is uneven and asymmetric. There is a central ridge of material, and various protuberances and trenches.<br/><br/>Item #7 is a list of recorded meteors spotted over the USA since 2005. The events are recorded by number of witnesses, the date and time spotted, which state they were spotted over, whether or not there was an accompanying sound (either concurrent or delayed), and whether the meteor broke up. Of note is the increase in reports between 2005 and 2013 - the latter year had six times as many reports as the former. The cynic in me says that's just because word got out about the website, but...<br/><br/>Item #9 looks to me to be a 3D acoustic spectrum... I'd say the most important part of this one is the accompanying text in the<strong>Brief</strong>.<br/><br/>Item #12 is a digital painting of an SR-71 reconnaissance plane.  Pretty picture, but again I'd say the text that comes with the link is the more relevant part.<br/><br/>Item #13 is a sketch of runic/maybe hieroglyphic set of symbols. There are four, arranged in an inverted diamond. The top one is labelled as 'The Monolith'. It looks like a stylised eye. Bottom left is labelled 'Ero, City of Gods'. It looks like an upside-down version of the Nordic rune for F. The bottom centre is labelled 'Sirra, City of Men', and looks like a stylised Y with a dot inside the fork. The bottom right one is labelled 'Ibarra, City of Demons' and looks like the Greek letter Mu without the leftmost stalk.
