1. <Anbaric> Redirects sunight
<Anbaric> for white
<Anbaric> sunlight hits it, it sends beam in one direction
<Anbaric> beam hits something, it glows at ll16
<Anbaric> if it hits another redirector, ll goes down by one
<Anbaric> but keeps going
<Anbaric> Black one doesn't emit light when hit, but splits beam

2. <dark2phoenix> Make dark ones like spring boards, light ones ladders?

3. <simpman> dark blocks can be used to make nether portals? I don't know
<simpman> Would be cool to have nether portals able to be made of different blocks, obsidian is played out
(I don't think this one is possible without making a custom portal which is meh)

4. <tEHFRECKLEZ> I want one that explodes or damages mobs

5. <dark2phoenix> How about dark ones are like pressure plates

6. <simpman> They could also have special properties, like making your multi-block structure from black will give you more storage

7. <Zeeth> Oh. Wait. Ideas for dark and light xychorium function blocks with no inventory? Dark: pulls mobs toward it when powered by redstone.

8. <dark2phoenix> Make the white ones pass through
<dark2phoenix> Like a secret door

9. <Zeeth> Light: Emits an aura of defense. Potion effect, Resistance I for 6 secs, like a beacon.

10. <Stevetech> You already have 3 of the 4 elements convered. Earth, Fire, Water. Mayhaps something "wind" related? Walking on light speeds you up and dark slows you down?
<Stevetech> Could be useful for walkways/mob traps
