Just finished a blink reminder app https://blinktracker.app a couple of days ago. Monitors your eyes' blink frequency with a camera and also reminds you to take regular screen breaks.

Somewhat ironically after giving up smoking I take too few breaks and get blurry/dry eyes after long days. The app is a bit overengineered and comes with an api in case you ever wanted to start controlling stuff with blinks. Currently Windows only.

Looks to me like Bob would end up with Lisa's item and a tax-deductible donation when he nukes the contract.
