It's a blackboard, not a lasagna.
Lavagna is a "no frills", collaborative, blackboard, ideal for simple sketches during online meetings. You have just a black screen, without icons or buttons cluttering your beautiful drawings.
Just you, your peers, and your chalk.
| Button | Action | Note | |--------|----------|--------------------------------------| | C | Color | Change the chalk color | | M | Grow | Grow chalk size 2x | | N | Shrink | Shrink chalk size 2x |

shell
lavagna --collab-url wss://lavagna.devand.dev/YOUR_ROOM
Change YOUR_ROOM
to whatever you prefer. If you do the same from a different
computer, whatever you draw is visible on the other side (and vice versa).
