\end{tikzpicture}Do you mean something like $\bullet$dwsmith said:Code:\begin{tikzpicture}[scale = 1.5] \draw (0,0) circle (1cm) node[anchor = north east]{$\text{S}$}; \draw[->] (.70710678118,.70710678118) -- (1.4,1.4) node[anchor = south east]{$\vec{n}$}; \end{tikzpicture}
I have made a circular surface with normal vector. How can I make blob instead?

Maybe there is a way to change the size of this \bullet
In order to create a blob in tikz, you can use the "plot [smooth cycle]" command to draw a closed loop. By adjusting the coordinates and adding curves or loops, you can create a blob shape.
Yes, you can change the color of the blob by using the "fill" command and specifying the desired color. You can also add shading or gradients to the blob by using the "shade" or "shading" commands.
You can add text or labels to your blob by first creating a node using the "node" command. Then, you can position the node within the blob and add the desired text or label using the "text" command. You can also adjust the font, size, and color of the text.
Yes, you can animate the blob in tikz by using the "animate" package and creating a series of frames that show the blob changing shape or position. You can also add animation effects such as rotation or scaling to the blob.
Yes, you can save your blob in tikz as an image or PDF file by using the "standalone" document class and compiling your tikz code. This will create a standalone image or PDF of your blob that you can use in other documents or presentations.
