| When I originally saw that game I wondered how they could build
| it so cheap until I realised it was just an LED on a plastic pen.

| I love this project. In high school I started a group in my
| school district to collect or buy the remotes and install these
| in teacher's classrooms. We installed over 200 of them! Back then
| there was a healthy community online of people porting the
| software and building and selling the infrared pens. I learned to
| solder for the first time turning dollar store plastic pointers
| into infrared pens. The best setup was to use a 3D printed clip
| to mount the remote to the drop ceilings in the classrooms- this
| made it more difficult for a student or teacher to obstruct the
| camera while using the board and made it harder for someone to
| accidentally knock the remote which would then require the
| teacher to recalibrate (a process involving tapping targets at
| the boundaries of the projected screen).

| wall-sized photoshop. That was fun. Thanks for the memory :D

| I used to think that remote whiteboards (e.g. Google Jamboard)

| proven very productive.
|
| Now I'm not so sure. It seems like some _ad hoc_ communication
| can be switched to a scheduled-presentation format, which allows
| the presenter to create online slides / diagrams. Pro: the
| presenter may think through his/her ideas more before soliciting
| feedback. Con: less spontaneous discussion, and harder for others
| to present alternative ideas.
|
| Anyone have thoughts on this?

| It works particularly well if you're already accustomed to

| some feedback, if you get a chance to try it.
