how do these blend in with the original graphics? (i'm afraid they won't but maybe that can be solved somehow, overlay graphics etc.)
The tiles themselves blend in pretty good already with the original sloped graphics as you can see from the screenies. I have drawn (read copy/pasted) the waterlines the same as the original tiles, so the waves match. For the sides I have made transition pieces from grass to sand (as you can see in the screenies), only the transition from sloped sand to flat grass is not gradual yet, I have some work to do on that.
Did I ever tell you what a lovely chap you were?
lol, calm down sailor
Geez, Quast, I'm sure you done this for the screenies competition
It was indeed one of the inspirations, however I doubt if it will be ready in time to be used in the competition
Let's just say, to play fair I want to have a public release before I use it in the competition.
Anyway, how about we contact Whopper for his magnificent illusion of beach ? Maybe he can make something better...
Seeing those screenshots also inspired me to make this, however making those kind of beaches (especially the watercolors) will be very very difficult (if not impossible) due to the limitations of the color palette.
If you made some of the tiles industries, they could be made to accept passengers...
Good suggestion, however I find it tough enough to code stations and objects, industries is not on my to do list (yet). However, I will eventually release this set under GPLv2, so any coder can pick up the graphics and code them into industries.
And finally a little bit of news, thanks to the help from Wallyweb over at Simuscape I think I will be able to animate objects! (he wrote a very good tutorial over there) So this might get a bit more interesting.
If you're working in NML, you can look at OGFX+ Landscape's Wind Turbine for a good example of animated objects: 
(as they will be animated too !)
