Your phone screen becomes the drawing pad. Works on Wi-Fi or mobile data — nothing to install.
Preparing…
Point your phone camera at the code and open the link.
Turn the phone sideways — the pad matches this screen.
Draw with your finger. Top-right of the phone is top-right of the board. Lift to stop.

Tablet mode — the trackpad becomes the board
Open the whiteboard folder and double-click Start Trackpad Bridge.command. A Terminal window opens — leave it open while you present.
Click Tablet in the bottom bar. Its dot turns green when connected.
Press Space. Now the trackpad maps to the whole screen: touch to draw, lift to stop, and touching another spot jumps straight there — top-right of the trackpad is top-right of the board.
Press Space again to get your normal cursor back. Two fingers still zoom and pan.
