Pick pro gear right off the pegboard wall, select rental dates, and get an instant breakdown of shift rates and refundable deposit.
- The Challenge
- Make contractor tool rental transparent with zero hidden deposit math or phone tag.
- What’s Under the Hood
- Visual pegboard catalog, multi-day shift calculator, and instant reservation summary.
- How it is built
- Canvas relights the tool wall; Matter.js handles object physics. JavaScript connects the calendar to the rental estimate. Manrope and JetBrains Mono use SIL OFL licences; illustration sources are listed in the demo.
- Try It Right Now
- Select tools from the wall and change rental duration to see the shift rate recalculate.

The wall shows which tools are available for the selected days. Change the dates and choose a tool to see the rental and deposit calculation. This is a demo; no booking is made.
