Place microscope on desk so can sit in chair and look with the microscope.
Put corner of laptop screen under microscope. Prop up other half of laptop (e.g. with textbooks).
Get the Snap stage area underneath the microscope by either:
- Pressing the F11 key to make the web browser full screen (press it again to undo full screen).
- Moving the web browser window.
Focus the microscope so can see subpixels clearly.000100green0100blue0100rgbvar stage = this.parentThatIsA(StageMorph),
