>>6771103There's few adaptations of his work as far as media goes. He's mostly an artist and as such appreciating and seeing his paintings is the best way to start
After that, Alien/Xenomorph was designed by him, as was the creature from Species (film)
There are 2 videogames that use his artwork as background images and sprites called Darkseed and Darkseed II. They're old and might be difficult to get running on modern machines. Their quality is a bit divisive, some love them, some hate them/mock them. Try finding some playthroughs first to see if you like them
McFarlane toys has a sculpture of one of his works called LI II. Looks quite nice but can be expensive these days
There are actions figures of the Species creature and a few other sculptures and busts and whatnot of his work or inspired by his work. Prices vary wildly so it's best to just search for these yourself
Finally the Xenomorph is extremely popular and has hundreds if not thousands of merchandise available. Just take your pic, really
