Unfortunally the front and back of the walkway through the door need to be unmovable objects making this not a true hipster door.

Nevertherless, this project was a ton of fun and quite challenging. Especially the sideways "slider" that initially pushes rows upwards and the leaf bit that is used to avoid updating the feed tape.

For the timing circuit, I designed a feed-tape minecart ROM inspidered by a design used by Comet107 (   • Corner block challenge solution | the...  ).
The minecart ROM on itself is quite compact but considering the opening/closing sequence is not that complex, it is better to use a smaller design such as a normal feed-tape.
The volume (x*y*z) is 36x21x1 (including floor and the blocks above the floor )

Like with a lot of my builds, credit to RMC for being first (as well as making a way better version):

They made a full 1-wide 3x3 hipster door that I highly recommend checking out.
