 |BitmapIcons                |Simple example of how to display a bitmap image to the display.                                                        |
 |ChainedPanels              |Popular example on how to use the 'VirtualDisplay' class to chain multiple LED Matrix Panels to form a much bigger display! Refer to the README within this example's folder! |
 |ChainedPanelsAuroraDemo    |As above, but showing a large trippy plasma animation.                                                                 |
-|DoubleBufferSwap           |Advanced example of using a back-buffer (double buffering). Not useful for 99% of use cases.                           |
+|Smooth Double Buffer       |Example of using a back-buffer (double buffering). Not useful in 99.9% of use-cases of this library. Uses double the SRAM as well.          |
 |P6_32x16_1_4_ScanPanel     |An advanced example ('hack') on how to use this library on 32w x 16h 1/4 Scan LED Matrix Panel.                                |

+ It then flips between buffers as fast as possible whilst moving them as well - to give the impression they're both on screen at the same time!
