Here are some custom graphics which you are free to use in your own copy of NeoLemmix, if you wish.
:lemming: Traps for orig and ohno styles with improved/removed secondary animations
:lemming: ohno_brick - The stomper trap is now non-animated (unless triggered).
:lemming: ohno_bubble - The zapper trap now has a glowing animation rather than the 'zig-zagging barrel' one.
:lemming: ohno_rock - The lizard trap has more than twice the number of frames; its eyes now dart about randomly as well as occasionally blinking, similar to a real-life chameleon.
:lemming: ohno_rock - The weed trap is now non-animated (unless triggered) and is now identical to the original.
:lemming: ohno_snow - The icicle trap is now non-animated (unless triggered).
:lemming: orig_crystal - The large electric trap now glows whilst electrocuting, the electricity lines are a more "electric" colour, and the lemming glows white.
:lemming: orig_crystal - The small disc-shaped electric trap now has a scrolling shimmer, the electricity lines are a more "electric" colour, and the lemming glows white.
:lemming: orig_dirt - The rock trap is now non-animated (unless triggered); I have also included a version of the rock trap which drips less frequently, for those who prefer the blood drip animation.
:lemming: orig_marble - The stomper trap is now non-animated (unless triggered).
:lemming: orig_pillar - The rope trap's light is a brighter shade of green.
:lemming: orig_pillar - All spike traps (large and small) are now non-animated (unless triggered).
:lemming: Floater with red & white umbrella (high-res only)
Add this sprite to styles/default/lemmings-hr to give your Floaters a cute red & white striped umbrella!
:lemming: Shimmier sketch
This is a handy sketch graphic for the Shimmier which shows the height of the "Reacher" state, so you can see whether or not a lem will be able to grab the terrain above them. Add this to NeoLemmix/sketches to install.
:lemming: Legacy menu card graphics
Add these to gfx/menu to restore the "classic menu" look in your copy of NeoLemmix. There are 2 versions, with and without shading. The "with shading" version makes a nice alternative to the "new look" NeoLemmix menu.
:lemming: Custom panel graphics (various choices)
To give your panel a new look, add these to gfx/panel (gfx/panel-hr for high res). As of the 12.11 update, these graphics now include a semitransparent overlay for "selected", to simulate a button press.
