Glowing Obsidian

Glowing Obsidian is a block which only generates when the Nether Reactor is activated. Upon activation, the blocks that make up the reactor turn into Glowing Obsidian. Glowing obsidian is almost purely decorative, however this is hard to make use of in survival, due to the lack of being able to obtainin the block in the inventory, or pistons, which do not currently exist in the Pocket Edition.

Properties
As the name suggests, Glowing Obsidian is a solid block that gives off light similar to Glowstone, but slightly dimmer. It does indeed glow, but its physical properties are closer to Obsidian. It takes the same amount of time to mine as Obsidian. Instead of dropping itself, it drops a normal Obsidian block. The block will emit red smoke particles within close proximity to it so long as it exists, similar to the particles Redstone creates when activated. Although in the Nether Reactor the block seems to spawn items around it, it is not the block itself that acts like this, nor will it spawn items if placed normally. The block turns into obsidian after a short amount of time. Otherwise it is simply an aesthetic block, as it has the same blast resistance as normal Obsidian.

Obtaining
Glowing Obsidian cannot be retrieved from the nether reactor, instead regular obsidian is dropped. There is a slight delay when the 4 gold blocks that are part of the nether reactor setup turn to Glowing Obsidian however, and so can be 'saved'.

Trivia

 * If the Nether Reactor Core is mined out while the Nether Reactor is active, the glowing obsidian will not turn into Obsidian after the reactor deactivates. This also causes the reactor to stop spawning items.
 * if you mine out the gold blocks before they are changed to glowing obsidian, you keep the gold blocks and the Nether Reactor keeps spawning items
