The Islamic Society of North America (ISNA) is a Saudi funded Wahabbist group. Its logo is in the shape of a mosque with a crescent topped minaret and a crescent topped dome. Here is the ISNA logo juxtaposed to a similarly shaped mosque from Uppsala Sweden:
Both configurations have upturned crescents. The difference is that the arms of the ISNA crescents are lifted symmetrically, while the Uppsala crescents have one arm above the other.
On actual minarets, the Uppsala configuration is the norm, seen also in this photo of the Abdul Gaffoor mosque in Singapore:
There seems to be only one example of an actual minaret that is to be built in the ISNA configuration. That is the Tower of Voices minaret from the planned Flight 93 memorial:
Two views of the Tower of Voices minaret, showing an Islamic-shaped crescent at the top, with its arms reaching symmetrically up into the sky. (Source images here and here, originally from the Memorial Project’s design competition website.)
The up-tower view shows the symbolic Islamic heavens projected against the sky while the symbolic lives of the 40 heroes literally dangle down below. Murdoch had to do this in order for his Crescent of Embrace design (centered around a giant Mecca-oriented crescent) to be a proper mosque. The 40 infidels could not actually be honored in the design. They had to be depicted as symbolically damned.
Murdoch actually repeats this theme in the central crescent, where the 4 extra translucent blocks (one for each hijacker) are all placed in the symbolic Islamic heavens (the crescent and star parts of the structure), while the 40 translucent blocks inscribed with the names of the 40 heroes are all placed outside of the symbolic Islamic heavens.
