Nice work! So much better than the existing flags, both the design and the well thought symbolism. Though Puerto Rico’s flag hardly needs changing IMO, it is already great as it is.

Nice and well thought out flag! It ticks all boxes for a good design.

I think I prefer this to the most famous keystone proposal. Putting the keystones in the middle make them more clearly look like keystones, rather than just a strange middle field. Matching William Penn’s coat of arms is also a nice bonus.

Popular “keystone” proposal for reference:

No idea why it’s a gif. I just linked to it from that webpage. It doesn’t display a play symbol in the browser. But it is a good call from you, showing why it’s better to avoid gifs for static image. Nevertheless, the position of the play symbol is quite pleasing.

Strange flag for a strange country. The whole story and the person D’Annunzio are quite unique and fascinating.

Glad to see this series here! I hope you keep posting!

Regarding the Cabinda flag, it seems to me that the color combination is not working too well. Maybe because its not very “vexillogical” colors? Yet, orange and blue are supposed to work well together, but maybe the yellow in between ruins the effect?

Here you go!

Minnesota does have an unusually large population with Nordic ancestry. I guess that is the reason for the Nordic cross designs

Yeah, I agree. I also prefer the version where they did not change the green or the bending of the crescent. Apparently that was the initially presented proposal.

The cars are about 10 pixels long, the loop about 200 pixels in radius. Assuming the cars have a typical length of 4.7 m, this would give a loop radius of 94 m. To create a centripetal force large enough to counter-act gravity at the top of the loop, you need a speed v_top such that v²/r=g. With g=9.8 m/s² and r=94 m, this gives a required speed at the top of v_top =sqrt(gr)=sqrt(9.8⋅94)=30,4 m/s=109 km/h=68 mph at the top.

However, the car would lose speed while while ascending the loop. Assuming that the kinetic energy of the car is converted to gravitational potential energy losslessly, and that no energy is added while ascending (giving some safety margin), it would need the kinetic energy at the bottom:

mv_bottom²/2=mgh+mv_top²/2 =>

v_bottom=sqrt(2gh+v_top²)=sqrt(4gr+gr)=sqrt(5gr)=sqrt(5⋅9.8⋅94)=67,9 m/s = 244,3 km/h = 151,8 mph.

This would be a recommended minimum speed on this road.
