I’m not the following the trends on any social networks so I’m possibly the least likely to know 
Personally I would like to try making objects that include both milled parts and other things:
- wood and (actual) stained glass would be great (to learn how to cut glass, at least)
- wire inlays: there was a thread recently about this and I bought some EL wire, I think there is great potential in that idea.
- I have always wanted to combine CNC and 3D printing, I’m still looking for the right project for this. It’s easy for objects that serve a purpose, but much more difficult for objects that are supposed to look great.
Believe it or not I do not own a fly cutter. Buying a decent one is on my todo list, but I hardly ever feel like I absolutely need one. Probably because I have a SO3, not an XXL, so the pieces I’m cutting are never large enough that surfacing with a small diameter endmill is a real problem.
I bought liquid dye, and mica powders, and usually use one or the other or both. Honestly, I don’t know what I am doing when it comes to coloring epoxy…I’m sure other folks here would have tips.
I also get my epoxy off Amazon, but there again I go for whatever I can find that is cheap, because for now I only use it for inlays, so I don’t think the quality of the epoxy matters much. If I were doing large river tables or countertops, I would put more effort in finding/buying the good stuff. I’m also frustrated that you guys in the US have lots of options for quality epoxy products, and I can’t seem to find similar options locally (but then again I have not tried very hard).
In French it’s “platane”, I had to look up the translation and it seems to be “plane (tree) wood”. Its face grain sides are not very interesting (see underside of the box cover), but the endgrain sides show that leopard-like pattern indeed.
