The dome was made with size 3 units, I didn't try to downsize but probably that is possible.
As not everyone has 3348 magnets, here is a table for smaller versions of the spiral:
1. smallest unit: 65 dots
2. size 2 unit: 130, total 195
3. size 3 unit: 213, total 408
4. 314, total 722
5. 433, total 1155 dots for a spiral with 5 units
6. 570, total 1725
7. 725, total 2450
8. 898, total 3348
The spiral can be made even larger, as shown in the next video 'Enlarged spiral'.
9. 1089, total 4437
10. 1298, total 5735
11. 1525, total 7260
12. 1770, total 9030
