Introduction

Tiny Megademo Framework

History of tiny effects

Sizecoders think in size categories. For MSDOS, these categories are 256b, 128b, 64b and 32b. These are the standards of one of the biggest demoscene archives, www.pouet.net. There is no 16b category, although many tiny effects can be implemented in 16 bytes. Almost of the effects of "Memories" have been coded and optimized by me before, and mostly the implementations were attempts to reduce an already existing effect in size, or do something similar in less size. Reducing the size in this case means, reducing it to the (one of the) next lower 2^N category. For example i might have seen an effect done in 33 to 64 bytes, and then reduced the size to 32 bytes or less. Almost everytime i moved an effect to a lower category, i submitted the resulting tiny program to a demoscene party which allowed remote entries in the 256b category and/or published the result to www.pouet.net . In this section i will introduce the effects and mention the origins and authors.

Array of chessboards

The origin of this effect is my own "Kasparov 16b" from 2018 (https://www.pouet.net/prod.php?which=75912) apparently i "had this piece lying around, stuck at 17 bytes and not that beautiful, until i found a trick ;)" (quote from the release notes) There was a similar effect in 32 bytes before : "ew" by headcrash from 2003 . (https://www.pouet.net/prod.php?which=17567) In this case, my design goal was to show "real" chessboards of 8x8 fields and recognizable dark and light squares, as well as the correct orientation of the single chessboards, meaning that the bottom left corner (a1) has to be a dark square. (source!) For "Memories", the effect had to be reimplemented with another approach of writing to the screen to work with the framework, also the scrolling direction was changed to be different from the "scrolling tilted plane" effect.

Zooming circles

The zooming circles were supposed to be entered to a demoparty as a 32 bytes intro, but i never actually did it. There is no real predecessor in 64 bytes, because in the 64b category much more complex effects are possible. The zooming circles were the result of desperately trying to reach the 32b category for a circular "tunnel" effect, for that my own record is still 52 bytes ("Neontube" - 2016)(https://www.pouet.net/prod.php?which=66808) which in turn was the optimization of the all-time-classic "constant evolution" from ryg/Farbrausch (2003) (https://www.pouet.net/prod.php?which=8697). In the zooming circles routine, the distance and the angle are removed/ignored, so that the 32b category could be reached.

Scrolling tilted plane

The scrolling tilted plane is one of my own releases, "floorcast 32b" from 2018. Floorcasts have its own history in sizecoding, the effect was brought down stepwise from 128 bytes to 32 bytes. The versions differ in the number of plains, some show two plains, others only one. For the "floorcast 32b" release i specifically decided against the "XOR" texture, whereas in "Memories" i used it again.
