Dmitry Tyurnikov is a Russian programmer who enjoys modding games. He tends toward changing game physics using many of the mathmatics in Hyperrogue.
He has created a SPD v3.0.2 mod that uses hexagonal tiles. Although not a new concept (D&D maps used hex grids), so far as I know this is the first implimentation of hex grid physics in a PD mod.
His mod does not show up on Reddit, whose members were very anti hexagonal when proposed by others in years past.
Nor does his mod appear as a fork of SPD.
If it is on Playstore, Google’s 5h!tty search engine doesn’t reveal it. Although the code is posted on Github it does not appear in Micro$oft’s 5h!tty search engine as a new SPD mod unless searched specifically by name. It was incidental to my researching another mod that I stumbled upon this one.
this is both sick and holy fUCK MY EYESSS
