# Complete Overlay Design
## Nonfunctional Requirement
The **user interface** is enhanced by designing a unique membrane overlay.

## Options
If the adhesive allows, the overlay may be heated and removed (supporting the hackability requirement.)

## Constraints
The graphic design is **silkscreen printed,** reducing color choice (a cost constraint) and obstructing gradients.

## Functional Requirement
The material choice is **250μm (micrometers) polycarbonate** with a 250μm peeled adhesive layer.
