Hahaha this must be the least comfortable shape of keycap I've ever seen xD . But it looks really awesome actually xD .
The drill core is an emotional- piece for me..
The concept of Spiral Power.
To challenge those who merely wish to remain in place.
To constantly improve and grow.
To evolve beyond mere pleasure seeking.
To Incorporate the universe itself into ones perspective..
These are the ideologies I feel was highlighted in Gurren Lagann. And the drill core, the central power, something simple in concept, then Magnified and refined an infinite fold..
Those were the things on my mind when making all the improvements to the cap.
