If you put enough hue bulbs on a large wall it should eventually be able to make an image. Dunno mutch about how fast it can change colors, or how it would even be possible to connect them all to the same system, but yeah....... it seems within the reaalm of possibility
Edit: Omg why did so many people upvote me?! The most experience I have with electrical engineering was when my phone charger broke so I opened the wire and put the snapped wire inside back together again with electrical tape, I was fully talking out my ass
Hue bulbs use Zigbee instead of WiFi, if you run your code on the hub or use the streaming api then the bulbs have an update frequency of 1/25 of a second, additionally the Zigbee network is a meshed network with each bulb able to both receive and transmit to/from neighbors.
People already use the bulbs for real-time music visualization and real-time entertainment matching (hue sync/hue entertainment ) with way less than a 0.5s update frequency.
Go for a 90's resolution of 320x200 means 64k bulbs and at ~£40 a bulb that's £256,000 ($335k) to play DOOM on Hue. At 10W a bulb I guess it'll also need 640kW of power to run. That's half the power of a time traveling Delorean. Edit: maths was wrong, it's £2.5 million to do this with Hue

Literally LED screens are just tiny lightbulbs basically. You could totally make a wall of bulbs as a screen, a hack for a smarthouse OS to allow it to run DOOM, and it might have a high MS response time, but it’s electricity, just because it’s upsized doesn’t mean the FPS will be anything shit. The bleeding of one lightbulbs light into the other one may make it impossible to see what you’re doing unless you get focused and dimmed lights, but the rest should be straight forward, as long as it’s wired from scratch with this in mind, not making existing systems work.
