Logo
Antenna is the logo in use; the others are the concepts drawn for it. Each is shown full size on light and dark, at favicon size (32 and 16 px) and next to the wordmark. assets/generate_mark.py draws them all.
AStack
The database cylinder everyone knows, with two eyes on its top band: a database that looks back at you. The grooves read as a smile at full size and as the usual disc lines at favicon size.
The accent variant, with part of the mark in the theme's accent.
BDiscs
The same cylinder cut into three discs with air between them, the eyes on the top one. The gaps make it read as a body of segments rather than one drum.
The accent variant, with part of the mark in the theme's accent.
CAntennaCurrent logo
Discs with an antenna on the head disc: a stem and a ball rising from the top face. The smallest addition that turns the stack into a droid; at 16 px it is a single dot above the head.
The accent variant, with part of the mark in the theme's accent.
DEars
Discs with ears on the sides of the head disc, square eyes and a mouth slot. The fullest face of the four. The mouth is a hairline at 16 px, so the compact form drops it.
The accent variant, with part of the mark in the theme's accent.
ETree
A B+Tree of three nodes: a root with one key over two leaves with two keys each, joined by the leaf link. The compact form drops the keys.
The accent variant, with part of the mark in the theme's accent.
FFan
A wider tree: a root with two keys over three leaves, the struts dropping from between the keys, the leaves linked left to right.
The accent variant, with part of the mark in the theme's accent.
