Amazing!

I always thought that the best we could do for targeted drug delivery was an adenovirus. But after seeing that parasite being only slightly bigger than a red blood cell, I think we can do better...

Never before have I seen the message "Firefox has been terminated by the Linux kernel because the system is low on memory". Thanks for a new experience!

I do like the visualization.

Great visualization! It would have been nice to zoom out to a view of the world from space at the end, since this is really the max size of life as we know it (n=1 so far).

I didn't know tardigrades can be big enough to be seen with the naked eye. Apparently big enough to be seen but not big enough to be recognised without magnification.

I don't understand how the location of a 377 foot tall tree could be kept secret. Wouldn't that type of thing be visible in satellite imagery at the very least?

My main takeaway was that I had no clue how large Krill can get. To think that Antarctic Krill is as long as the Bee Hummingbird is tall is absurd to me.

One error I think I spotted: Wooly Mammoth atill lived 4000 years ago in Wrangel Island but the the website says it got extinct 10,000 years ago.

Nit: the tool-tips on the action icons in the top-right aren't consistent.

When music is playing the tool tip is "unmute" which is a verb. It should either be "mute" (to indicate what clicking will do) or "unmuted" (adjective) indicating the current state. Similarly, when the music is muted the tool-tip should either be "muted" or "unmute".

I'm not sure _which_ is wanted (verb or adjective) because the ruler tool-tip uses "Hide Ruler" and "Show Ruler" (verb), while the units tool-tip uses "Units: imperial" and "Units: Metric" (adjective). The info tool-tip ("Info") is also an adjective.

For consistency, I'd use a verb-phrase in all the tool tips:

- "Show info"

- "Switch units to metric/imperial"

- "Hide/show ruler"

- "Mute/unmute music"

I mean, I know this is pedantic nit-picking, but the site is so perfect, what else am I going to do?

EDIT: Nevermind. Perhaps it was an ad that I clicked on. Lots of comments here indicating they don't see it, and some that did.

My Original comment here (too late to delete):

Beware. When you reach the end there is a "more projects" button. In there is a cute IQ test (possibly appealing to the HN crowd). When you reach the end of the test it asks for email, and then ultimately wants $1 to get your results. If you pay by credit card due note that there is an auto-checked box for some $29.99 per month subscription for... something.

Fun to see the Jerboa. I recently read a family history written by my uncle and he believes this is the source of our family name.
