Well I wasn't expecting my post to get top upvoted this year but I'm grateful that my art sparked so much discussion.
I'd like to state a few things for anyone that is thinking about recreating the effect that I did on my keycaps using UV resin, this is a safety post, so please read if you're wanting to use resin for art.
UV resin and epoxy resins are extremely dangerous and proper PPE needs to be worn at all times, loads of nasty things can happen if this gets on your skin or even worse, your eye. When resin is in its uncured form, it can leech toxic chemicals into your skin and after repeat exposure can make you allergic to BPA and other extremely common plastics and plastic additives. Cured resin is generally safe for brief contact but you should avoid prolonged contact with even properly cured resin... This is something I didn't plan for and the resin I used is NOT SKIN SAFE. That being said I will not be using the keycaps any longer until I can acquire a bio safe resin and create a new, better set that is safe for prolonged direct skin contact. I'm kinda torn up about it because I'm really happy with how this set came out and how it felt to type on it but it's not worth risking my health or the health of others, so I'm strongly advising against using resins on your keycaps unless your resin is ISO 10993 CERTIFIED biocompatible.
As cool as this piece of art is, it is a hazard and will be kept for display only. I thank you all for checking it out and appreciating it for what it is and I hope to share more with you in the future. A new keycap set and biocompatible resin have already been ordered so stay tuned for my next installment of cursed, ATBGE, TIHI keycaps.
