 ## Library & Tooling Updates
 
+### [hexasphere] v1.0
+
+![hexasphere example gif](hexasphere.gif)
+
+The [`hexasphere`] library provides a customizable interface for subdividing 3D
+triangle meshes. Custom and stateful interpolation functions can be implemented
+as well as per-vertex attributes.
+
+All that's required to define a base shape are the initial vertices, triangles
+based on the indices of the vertices in the initial vertices, and numbered
+edges. As long as the winding of the triangles remains consistend throughout
+the base mesh, all of the resulting triangles will retain that winding.
+
+This library also provides a few interesting base shapes (which can be used alone
+if the shape is not subdivided):
+
+- Icosahedron
+- Tetrahedron
+- Cube
+- Square Plane
+- Triangle Plane
+
+(All of which are pictured above)
