what about a canvas that is online for way longer, like a couple of weeks, BUT it is read only except during peak user times, and/or the weekend.
give more time for attention and hype to build up, while still restricting the time people have to place pixels. it would also give people who want to place as many pixels as possible and make bigger projects have time to go outside and touch grass, as well as use the 6/6 pixel stacking.
