I often develop 2D games. I would like to know if there's a program like EvalDraw out there, that makes it easy to quickly make (for example) a square, out of a black quad, and then write some shader code, and see how that shader code modifies the square in realtime.

That would be really great for my future development processes.

Edit: The shader tool must work with HLSL.

Try these:
http://www.advsys.net/ken/polydraw.zip < - author of EvalDraw
http://www.iquilezles.org/apps/shadertoy/ < - you must have good browser :)
http://shazzam-tool.com <- HLSL
http://marino.boletus.hr/download.html <- HLSL

Is there an HLSL equivalent for ShaderToy? – Mathias Lykkegaard Lorenzen Jun 7 '11 at 16:19
I think, there is no HLSL equivalent, beacouse shadertoy use WebGL, and WebGL use glsl. Mayby somewhere is equivalent in silverlight, but I don't know. – piotrek Jun 7 '11 at 16:40
I found this shazzam-tool.com - there is HLSL – piotrek Jun 7 '11 at 16:48
Yes, but specifically for WPF and Silverlight. Are there any for general XNA stuff? – Mathias Lykkegaard Lorenzen Jun 7 '11 at 23:26

RenderMonkey and FX Composer were both tools like this, although they've been relatively abandoned recently. 3D modelling tools like Max or Maya often usually have shader/effect/material pipelines built in, but they are probably prohibitively expensive.

I was looking for an editor yesterday and instinctively visited the Nvidia and ATI developer sites. I wonder why these have been left by the wayside? – George R Jan 16 '12 at 4:17
I would venture to guess it's due to the fact that shader semantics tend to be coupled to their associated rendering framework or engine, and as those engines increase in complexity a general-purpose tool becomes more and more difficult to write. – Josh Petrie Jan 16 '12 at 4:20
