In regards to the planetarium: I'm not gonna lie, at first I was won over the most by the second one, the tall box. I think that was because I am a New Yorker, and low-slung buildings are far more popular in Sunbelt cities like Austin.
However, it also reminds me a lot of the Rose Center for Earth and Space here in NY, as well as the Wyly Theatre in the new Dallas Arts District, which makes me worry about it coming off as unoriginal.
Then I saw the last one and I was blown, especially by that sped-up night render!

As much as I don't usually go for lower buildings, that looked straight out of the Jetsons

and the transparency and openness it appears to have makes it's low and wide shape feel extremely light and airy. I think that it would definitely boost Austin's profile to have a planetarium and science museum that is truly ultramodern.
Pretty much dope as hell hahaha
