Smoke Globe (3.5e Equipment)
From D&D Wiki
Smoke Globe: These glass spheres are popular with mages that smoke; they draw the smoke from the air and use it to create displays within the globe. Typically displays are current weather, landscapes, ocean-scapes, star displays, portraits of people or monsters, etc. The owner can change the display at will and is only limited by their imagination and the fact that everything is in shades of grey. This item clears the air in a ten foot by ten foot area of all normal smoke every round.
For an extra 200gp the globe can be further enchanted to be in color.
