Powder Toy scripts:
- Alchemistry - Several elements as they were understood in antiquity, as well as some transmutation reactions.
- Exotics - Bizarre particles and matter states, including tachyons (with time travel), negative mass and neutronium.
- Original tachyons - Superseded by tachyons in Exotics, but they function differently enough to include both.
Some of these are available from the Script Manager but may be outdated, these versions will always be up to date.
