I've made Christmas trees before: 🙂 [Traced Christmas Tree Example](https://forum.inductiveautomation.com/t/get-all-the-vertices-from-a-general-path/100184/3)

**For more fun:**  
Add a running timer component to the window. Then, put a custom property on the canvas called `value` and bind it to the value property of the timer to drive animations in the canvas.

**Example:** _(Using the Santa repaint event code above)_  
Modify the part of the code where the eyes and pupils are drawn, so they change with the timer value:

```python
# left and right eyes
graphics.fillOval(59, 121, 24, 24)
if event.source.value % 2:
	graphics.fillOval(113, 121, 24, 24)
else:
	graphics.drawLine(113, 132, 133, 132)

# left and right pupils
graphics.color = system.gui.color('white')
graphics.fillOval(68, 126, 11, 11)
if event.source.value % 2:
	graphics.fillOval(117, 126, 11, 11)

```

**Result:**
