Nicely done, but it contains some misinformation. For example, neutrinos with higher energy are not bigger. "The physical size of neutrinos can be defined using their electroweak radius (apparent size in electroweak interaction). The average electroweak characteristic size is âY¨r²âY© = n Ã- 10^-33 cm² (n Ã- 1 nanobarn), where n = 3.2 for electron neutrino, n = 1.7 for muon neutrino and 1.0 for tau neutrino; it depends on no other properties than mass."
The "shortest length confirmed" at around 10^-17 m is also untrue as the Large Hadron Collider probes distances up to 10^-19 meters or 0.1 attometers.
Also where did you get the "estimated size of the universe" since current observations suggest the global geometry of the universe is flat, hence the universe seems to be infinite in size.

I liked the initiative to do a second version of the classic flash app and the addition of animations, music, coloring and new elements (such as the size of a Minecraft World), but I hoped to see much more interesting information about stuff on this one and instead I just got relative sizes of everything. I was expecting that at least you would explain that anything smaller than a Plank just "doesn't make physical sense" or that the universe is constantly expanding, for exemple.
If there's going to be a third version, a mouse-over information box wouldn't be bad.
