TARDIS
A huge impact to the Time Lords are the TARDISes, or Time And Relative Dimension In Space. This is the Time Lords was of transportation using materialization, making a TARDIS able to disappear and reappear in another location. Materialization can make it so a TARDIS appears around an object or person but can also leave without some people, only when the operator wants. With the Time Lords knowledge of the Time Vortex, a TARDIS can also travel through time. A TARDIS has a chameleon circuit that assess the surroundings of a time and place just before arrival and change the exterior to resemble something commonly found in that time and place. Using time lord technology a TARDIS is bigger on the inside. The Doctor once said that the TARDIS goes on infinitively and is in a constant state of growth and rearrangement. This is why when the TARDIS gets damaged, it can repair itself, often looking slightly different.
Pictured in the first image is a regular Type-40 TARDIS, before the chameleon circuit has been used. When the Doctor visited earth in the 1960's, the chameleon circuit broke after his TARDIS resembled a police call box. The many TADISes used (up until 2011) are depicted above. The 12th Doctors TARDIS is depicted below.
