This clever chart by Lazaro Gamio shows changing interest rates set by the Fed and changing projections. The animation makes it.

Shrinking the Mercator projection to equal area
It’s been a while since we got our regular reminder that the Mercator projection is better for navigation on the tradeoff for distorted area at the poles. Neil Kaye provides an animation:

Interactive shows map projections with a face
We’ve seen faces as map projections before, but this is 63 projections on one page. Plus, you can click and drag to change the center points to see how different parts of the face change.

Immersive digital waves to visualize nature
FLOW is an interactive art installation by Maotik that represents real-time weather data in the form of digital tides and waves that fill a room.
I used 11 parameters to define the ocean form, we connect ourselves to a database and retrieve data such as sea levels, tide coefficient, humidity, weather cast, wind force, wind direction, weather cast, moon cycle, location, time of the day. When parameters such as wind force or sea levels will affect the movement of the sea others such as weather cast or humidity will change the colors.
How do I install this in my garage?

Physical demo of how all maps are wrong
We’ve seen many one-off projects that show the distortions you get when you project a map. There’s just no avoiding them, when you convert a 3-D object onto a two-dimensional plane. Vox demonstrates and explains with an inflatable globe.

A more realistic perspective of country sizes
Most of us have seen the True Size of Africa graphic that squishes multiple countries into an area we normally see as much smaller. This is because of projections, which places a spherical planet in a two-dimensional space. Different projections have different tradeoffs. Even the True Size graphic has issues.
This interactive by Zan Armstrong tries a different route by overlaying two globes against each other.
I was inspired to create this after reading a friend's account of his time fighting Ebola in Sierra Leone. He was frustrated with misunderstanding about the disease, including that a "school in New Jersey that panicked and refused to admit two elementary school children from Rwanda. Never mind that Rwanda is 2,600 miles from the epidemic area in West Africa. That’s the distance from my apartment in DC to Lake Tahoe."
Rotate each globe on the left to the areas of interest. The globe on the right shows two highlighted areas in the same view.
Nice.
